Small improvements to the devcontainer

[Nereuxofficial]

This removes a workaround no longer necessary to install LLVM and updates the rust-analyzer plugin to use the official name, although the old one is aliased to my knowledge.

A possible improvement to the build time of the Devcontainer image would be to utilize cargo-binstall to download the binary release for sccache. Let me know if that is a worthwhile improvement and i'll add it.

Should be fixed now. What are your thoughts on using cargo-binstall to speed up the container building process? @tokatoka @domenukk

[tokatoka]

what does it do?

[Nereuxofficial]

what does it do?

It would allow for the downloading of release builds of cargo subcommands from Github. In the case of sccache this would reduce the time on my local machine from over 2 Minutes to less than ten seconds.

[tokatoka]

you can add

Thanks!
