Cleanup Templates/Issue-Links

[mhochk]

Cleaning up (and sometimes fixing) various 'New Issue...' links and their associated templates.

• Removes URL params already handled by corresponding template files
• Removes references to template files that don't exist
• Fixes a few template files that were improperly formatted
• Corrects/restores a few references to labels that were slightly off
• Misc smaller fixes (assignee updates, tracker links being off)

This does not address:

• Issue areas that don't have a template file. This change does not make new files for them.
• References to labels that don't appear to have ever existed. This change does not remove those references. If those labels are created they should "just work".
• References to assignees that fail for reasons more complex than a typo. There are a few, for example, that appear to be valid users, but can't be assigned - most likely because they aren't added to this repo. This change does not remove those references. If those users join the repo things may "just work". If not, at least the intended target is still discoverable.

Pull request overview

This PR cleans up issue template links and template files across the repository by removing redundant URL parameters that are already handled by template files, fixing improperly formatted templates, and correcting label and assignee references. The changes streamline the issue creation process by consolidating configuration in template files rather than URL parameters.

Key changes:

• Removed URL parameters (assignees, labels, titles) from README.md issue links where corresponding template files handle these fields
• Fixed template file formatting (added missing YAML delimiters, corrected label assignments)
• Updated assignee references (e.g., guohuideng → guohuideng2024, phumai → kurtcattischmidt)
• Corrected label references to match actual GitHub labels (e.g., CSSTooltipPseudo → TooltipPseudo, PWA Widgets → Widgets)

@mhochk I've opened a new pull request, #1212, to work on those changes. Once the pull request is ready, I'll request review from you.

These &title= URL's are very inconsistent - might make sense to standardize (or remove the existing ones) as a follow-up.

[mhochk]

Though I agree that standardized titles would look nice, I don't feel strongly enough about their value to force that change upon all the various feature teams that chose their titles already.

If you (or someone else) chooses to try to standardize them in the future, please be sure to also sweep across all the titles in the various template files - as the &titles are only there in the URLs for those without a template file to provide the title value.
