Deprecate room=class; use room=classroom instead

[winstonsung]

Bug: #1355
Change-Id: I90545a86f84877fea5908fd097334b87b98682e7

Description, Motivation & Context

"classroom" is now a conpound word and being used more frequently than the old 2-word "class room" in English language.

The page "Tag:room=classroom" was created first.

The page "Tag:room=class" was never created as a non-redirect page.

Note also that documentation of tagging on the OpenStreetMap Wiki is not the final arbiter of 'correct' tagging.

## Test-Documentation

### Preview links & Sidebar Screenshots

<!-- Use the preview to find examples, select the feature in question and **copy this link here**.
     Find examples of nodes/areas. Find examples with a lot of tags or very few tags. – Whatever helps to test this thoroughly.
     Add relevant **screenshots** of the sidebar of those examples. -->

<!-- FYI: What we will check:
     - Is the [icon](https://github.com/ideditor/schema-builder/blob/main/ICONS.md) well chosen.
     - Are the fields well-structured and have good labels.
     - Do the dropdowns (etc.) work well and show helpful data. -->

### Search

<!-- **Test the search** of your preset and share relevant **screenshots** here.
     - Test the preset name as search terms.
     - Also test the preset terms and aliases as search terms (if present). -->

### Info-`i`

<!-- **Test the info-i** for your fields and preset and share relevant **screenshots** here.
     The info needs to help mappers understand the preset and when to use it.
     [Learn more…](https://github.com/tordans/id-tagging-schema/blob/main/CONTRIBUTING.md#info-i)
 -->

### Wording

- [ ] American English
- [ ] `name`, `aliases` (if present) use Title Case
- [ ] `terms` (if present) use lower case, sorted A-Z

@winstonsung I am not sure a deprecation is the right approach here to remove the tag. This came up before, so I wrote about it here https://github.com/openstreetmap/id-tagging-schema/pull/1357/files#diff-22e674f3d1da91695fbafd4d2c81f91246cfabab3d16dcf6492e6024797b4da5

We can wait for input by others to see if they would thinks this a good fit for the deprecation rules. However I suggest you look into the other methods mentioned in the linked section.

I am not sure a deprecation is the right approach here to remove the tag.

• If your task is small enough, a few editing sessions in JOSM will often do the trick.

• I know the deprecated.json would only show up on iD when editing the element with the tag, and that's what I intended to do.
• I've already done the clean-up by using JOSM.

No less importantly, don't "wiki-fiddle"
Both of your argument are false

1. Creation of documentation doesn't approve or disapprove of a tag
2. Your Taghistory URL is bugged. =class is still more numerous, and growing faster.

=class was supported by at least 1 application https://wiki.openstreetmap.org/wiki/OpenIndoor#Rooms

[winstonsung]

So we should do it in the opposite way?

[Kovoschiz]

No, you shouldn't do anything until you have asked and reached a consensus, besides following all the regulations. At least I'm indecisive on this.

2. Your Taghistory URL is bugged. =class is still more numerous, and growing faster.

Is there any known issue that caused the bugged diagram?

[mxdanger]

Thank you for this change! Even if this pull is not merged it's good that we at least have a tagging discrepancy resolved. I'm an avid indoor mapper so it's good to see this going somewhere.
