Enable GitHub Discussions for espressif repositories

[tosemusername]

Everything that goes in the here is a candidate for a Discussion on one of the Espressif repos, in addition to every issue that is filed in IDF repo that should go here, which is the first reason for this. And let's face it, Espressif's GitHub, especially ESP-IDF repo, is more popular than this forum. So all in all, no real friction, better organization (easier to manage, and there would now be a real alternative and incentive for not posting something which isn't an actual issue with IDF or other repos), and thus, less fracturing of the community (GitHub instead of GitHub AND this forum).
The second is that GitHub Discussion platform is just better (Markdown > BBCode, Dark-mode, Discussion topics can be tagged, answers can be flagged, among other pros).
The better access to folks from Espressif is also a plus, although I see how that can also be a con, but it can be managed through GitHub itself. An arguable con is the extra reliance on GitHub, but so long as GitHub can be trusted to be the only public mirror of IDF, I find it hard to believe this to be an issue.
