[Enhancement] More useful issues search link in the error message page

[opk12]

Is your enhancement request related to a problem? Please describe.
People don't search before opening a duplicate, even if they are given the link searched for existing issues on GitHub which points to

https://github.com/iv-org/invidious/issues

Describe the solution you'd like
The searched for existing issues on GitHub link should be prefilled with the exception class; or with the message, if it's the same for all users. For example, for #4498,

https://github.com/iv-org/invidious/issues?q=is%3Aissue+is%3Aopen+VideoNotAvailableException

The solution is to force a github issue template. There is a way to force to check a checkbox, this will 100℅ help reducing the duplicated issues.

With issue forms, the template cant be easily ignored (you can mark some fields as required)
Here's an example of how it looks (this is what's used for freetube bug reports)
