Add Adrian and Danny as FIP editors, remove Kaitlin

[luckyparadise]

I have included Danny and Adrian as new FIP Editors and removed Kaitlin. FIP Editors should let me know if there is somewhere else I should be updating.

@luckyparadise Someone needs to update the @filecoin-project/fips-editors github team and the @fip-editors slack group accordingly, but I don't have permissions to do so.

I've created a peer PR for the repo permissions in filecoin-project/github-mgmt#92

As discussed in this thread, @luckyparadise It would be great if you could also update the FIP editor expectation to document that for PRs that change the protocol design/spec or considerations, FIP editors should make sure there exists at least two appropriate technical reviews & approvals before considering the PR is ready to merge. You can do it in a separate PR; I am raising it here so a record of the request exists.
