Remove matklad.rust-analyzer until 0.2.853

[filiptronicek]

The rust-analyzer extension is having some troubles because of #336 - the build and packaging step succeed, but the extension doesn’t work in practice. Can we please unpublish all version until 0.2.853 (this is the last version that works)? I removed it from the publish-extensions repository so it won’t automatically publish the non-working versions. They seem to be willing to publish the extension directly after the aforementioned issue is addressed.

Note that we've also started submitting pre-release versions (see #386)). I don't expect publish-extensions to work very well with those (even the Code Marketplace has issues), so we do want to set up an Open VSX account and take care of publishing ourselves.

To clarify, do you want all versions removed that were published before 0.2.853 or after?

@brianking after: all versions worked until 0.2.867, which broke on OpenVSX. This means we want to remove 0.2.890, 0.2.880 and 0.2.867.

This is done, kind of. It seems to have caused another issue, see #816. Please don't upload a new version until we figure out what is going on.

The error has been fixed and this is now done and ready.
