Get rid of name com_github_nelhage_rules_boost and name it only rules_boost

We should get rid of the name com_github_nelhage_rules_boost and name it only rules_boost

[nelhage]

I'm 👍 to this change. It's also the case that I have less time for rules_boost these days, and you and @cpsauer have been taking on more of the maintenance, so I wonder if it makes sense to coincide a rename with a move of the repository to a new or existing organization. I don't have a sense of whether there's a place in the existing ecosystem that might want to accept it or if just creating a rules_boost organization or similar might make sense.

@zaucy Can we use your "Bazel Boost" orga for this?

[zaucy]

rules_boost and bazelboost are different approaches to utilising boost with bazel and including rules_boost under bazelboost may be confusing.

I think I'd prefer to keep bazelboost focused as a fork of "modular boost" with bazel support instead of a general org.

@zaucy Makes sense.

Other idea: We can move it to Bazel Contrib orga
