convert issue templates into issue forms

[NetSysFire]

Checklist:

• Added a description of the changes to the [Unreleased] section of docs/docs/CHANGELOG.md This is a purely organizational change that does not fit there tbh
• Added test cases to the relevant parts of the codebase No test cases needed
• Ran integration tests npm run test:integration (unsupported on Windows, please use WSL) See above
• All of my commits have verified signatures

As discussed. I made minor changes to the bug report template, like removing the Screenshots section as you can put screenshots anywhere in the issue. I also spotted an error in your bug report template, noting iOS twice, but this is fixed since I changed the section. I added the two urls so people know where to get browser/OS information. Unfortunately only the OS link is ad-free, I did not find any better alternatives for the browser one. Please review if that website is appropriate for inclusion here.
I also slightly adjusted the issue title for feature requests, though imo this could possibly be removed as well, and removed it for bug reports because they do not add any value to titles.

Alas, for config.yml it does not appear to support mailto: links. I tried and it did not show up at all, so I just set the url to your contact page.

The config.yml can only be tested on a master branch, which I did on my fork, but the two issue forms can be tested by viewing them directly, where github will render them. Click on the three dots and go on View file and see for yourself.

All changes apply instantly upon merging to master and you do not need to configure anything else.

Thanks! This'll help a bunch :)
