The previous regex would match the following:
```
abilityMods: [4, 2, 3, -3, 1, -1]
resistances: "[Some Link](note.md)"
```

So that that the first group (the link text) would match:
```
4, 2, 3, -3, 1, -1]\n resistances: "[Some Link
```
and the second group (the path) would match:
```
note.md
```

This commit changes the regex so that it doesn't falsely
match in these cases and instead just matches the actual markdown
link.

pf2e.css generated from the Fantasy-Statblocks-CSS-Development repo

As far as I can tell this is never used anywhere and doesn't appear to
have contents relevant to PF2e.

This allows conditional blocks to do things like check plugin settings
and whether other plugins are enabled. In particular, this allows
layouts to only show encounter buttons when the Initiative Tracker
plugin is enabled.

Separates out the name and value into their own HTML elements rather
than just rendered text so that we can style individual portions with
CSS. This change has no visible effects - existing statblocks should
look exactly the same.

This is instead of adding them to the text content itself. This allows layout authors to customize the appearance with CSS.

Thank you to MostTornBrain for valuable feedback! Most of this comes
from there :)

- Fix traits only showing when the trait property was present (even if
  alignment, size, or rarity was present)
- Add sign (+/-) to perception modifier
- Move Weaknesses before Resistances to match book layout
- Don't show Initiative Tracker encounter buttons if Initiative Tracker
  isn't enabled
- Show the initiative tracker view when the encounter buttons are
  pressed, to match the functionality of encounter buttons in the actual
  encounter blocks
- Bold save names
- Add sign (+/-) to ability modifiers
