Archive this repository

[guw]

I think there needs to be a discussion whether this repository continues to be an active source of truth or whether it is ok to archive. Development activities seems to have mostly stalled after I left.

FWIW, I am unable to do most basic things because I lost all permissions. I am also not motivated to continue asking for permissions every time I discover lacking something. Therefore I decided to continue at https://github.com/eclipseguru/bazel-eclipse/

I got updates to the Eclipse extension publishing to eclipseguru.github.io/bazel-eclipse/latest/.
