Add ghc-8.10.4 support

[jneira]

I was not aware of this one!

[Ailrun]

Me too, wow, we have quite a number of GHC 8.10!

What about 9.0.1? https://www.haskell.org/ghc/download_ghc_9_0_1.html

[konn]

GHC 9.0.1 related issue is already tracked here, pinned at the top of issues: #297

[ahmadrasyidsalim]

@konn, uh huh, my bad, thanks.

Circle CI is already struggling, so if you are planning to add more jobs to the matrix, please consider dropping others at the same time

[jneira]

Yeah, i was thinking in establish a policy by which we only are gonna support at most three minor versions (if there is no really good reason to do it)
So we would rule out 8.10.1 from all ci jobs, including releases.

[jneira]

@Ailrun we should do a release (a github simple one) with support for this, would you like to try it? no problem otherwise 😄

[Ailrun]

Will only a github release be enough?

[jneira]

I think so, at least for now, i dont want lose the possibility of doing quick github releases without hackage one

[Ailrun]

OK, I will try the release

[jneira]

Many thanks, feel free to ask for help whenever you find any barrier

+1 for release. Protecting users from stupid install hassles is (vscode-haskell's, I thought ?) number one feature and the reason I have been confidently recommending it to people. I saw someone getting tripped up by this in the Haskell matrix room today.
