[5.4] Email templates: make tags case insensitive

[e4e5Ke2]

Pull Request for Issue #46318

Summary of Changes

• Made the replaceTags method (of MailTemplate.php) case insensitive
  - Simplified some redundant code in said method with a closure

Testing Instructions

Insert tags into any email templates, written in upper or lower case. They should now work regardless of case.

Actual result BEFORE applying this Pull Request

E.g. the tag {sitename} as part of a mail template did not work. Only in upper case the tag {SITENAME} gets replaced with a value.

Expected result AFTER applying this Pull Request

Now tags work regardless of being written in lower or upper case. E.g. {sitename} will now work the same way as {SITENAME}.

Yeah, I didnt use AI for anything.. just saw a simplification since I was touching this method anyways. I'd be happy to contribute more fixes in the future, but not sure I like the tone here..

This single-line change wraps the $key variable with strtoupper() to convert tag keys to uppercase before creating the placeholder pattern. This ensures that:

Tag keys are normalized to uppercase (e.g., 'sitename' becomes 'SITENAME')
The placeholder pattern becomes {SITENAME} regardless of how the key was originally defined
str_ireplace() can then match {SITENAME}, {sitename}, {SiteName}, etc. in the template text

I have not tested this item.

Tested this patch on Joomla 5.4-dev.

Before applying the patch, only uppercase email template tags like {SITENAME} worked.
After applying the patch, tags work correctly in both uppercase and lowercase
(e.g. {SITENAME}, {sitename}).

Patch works as expected. Test successful.

Removed the closures, functionality should be unchanged.
