Remove unversioned config revisions API.

The response of the API is as follows:

Tasks

• [x] Move API to internal namespace (https://github.com/gocd/gocd/pull/7384)
• [x] Remove API docs (without release announcement) (https://github.com/gocd/api.go.cd/pull/548)
• [x] Remove API after 3 months (possibly in v20.2.0 release) (removed as part of https://github.com/gocd/gocd/pull/8102 PR in GoCD release v20.4.0)

It is documented API: https://api.gocd.org/current/#list-all-modifications.

Also, if we are removing this, we should also remove the diff API: https://api.gocd.org/current/#get-repository-modification-diff

[GaneshSPatil]

As of now, we've decided to move these API under internal namespace as the information exposed by this API is very specific to the internal implementations of how GoCD versions cruise-config.xml file.

The URL to access this API has changed from /go/api/config/revisions to /go/api/internal/config/revisions
