Upgrade to GitHub issue forms

[EmilyGraceSeville7cf]

Description

Switch to GitHub issue forms from legacy issue templates.

Motivation and Context

It's easier create forms via .yml files because VS Code and such editors can suggest autocomplete for them. Also there are linters for YAML and that's good. ;)

How Has This Been Tested?

I've created a sample repo and tested these templates.

Screenshots (if appropriate):

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

Checklist:

• My code follows the code style of this project.
• If my change requires a change to the documentation, I have updated the documentation accordingly.
• I have read the CONTRIBUTING document.
• If I have added a new file, I also added it to clean_files.txt and formatted it using lint_clean_files.sh.
• I have added tests to cover my changes, and all the new and existing tests pass.

I think I'm in favor of this in general, but I think this raises some questions about what to actually put in the form. With a template, it can be edited during submission if some parts make more or less sense in context. With a form, if we require a field that just doesn't apply to a given situation then the submitter has to put some junk in there which then in turn encourages sticking junk in there to begin with and it kinda defeats its own purpose. Just thinking out loud...

We can use an extra field «Notes» at the bottom for this case (but it's hard to imagine for me). Where any content can be placed. The idea is standardize issue content as much as possible. 😊

Hi @EmilySeville7cfg, this looks like a cool addition!
I agree with @gaelicWizard that there should be a room for general notes

Done. 👍🏻

I wouldn't add a link to Libera chat in there. There's literally nobody there, except one person who uses IRC and he's not actually there (just his account is logged in). Alsö, being IRC, there is no persistent chat. If someone asks a question and nobody answers immediately, then the question just disappears.

What about to use GitHub Discussions or Telegram? 😺

[gaelicWizard]

Telegram, Facebook, Signal, iMessage, &c all have the same issue: they're only for people who are already there. My +1 is for GitHub Discussions since the one place we already are is exactly here, but that's out of scope for this PR. (#2078)

I was just whining that you added a link to somewhere that's not actually got help to get. 😃

LGTM, @gaelicWizard what do you think?
