ConfigMap name missing UI validation

[nickwsuse]

Setup

• Rancher version: v2.7.5
• Rancher UI Extensions:
• Browser type & version: Chrome Version 115.0.5790.98 (Official Build) (arm64)

Describe the bug
When attempting to create a configmap that has a capital letter in the name, the request is made with no error checks and you get an api error page instead of an error on the UI (or the string being lowercased before the request is made).

To Reproduce

1. Provision a v2.7.5 Rancher instance
2. Log into the Rancher instance
3. Click into the local cluster from the home page
4. On the left side of the page, click Storage -> ConfigMaps
5. Click the Create button in the upper right of the page
6. In the Name field, enter at least one uppercase character and whatever else you want
7. Click the Create button on the lower right of the page

Result
Receive an API error

Expected Result
Receive a UI error (or the text is lowercased for the request)

Reproduced in 2.7.5, but in master (2.7q3) we get taken back to the config maps list. The request still fails. There's no error presented to user.

Tries the same with secrets, but the error is shown to the user.

Given the limited impact, i don't think this is a blocker, moving out of 2.7q3

#10794 was a duplicate of this however has been processed / resolved first, so closing this one

Edit: It's not quite the same, however will present the issue to the user correctly
