codelists: removed experimental tag from endpoint

After thought, I decided to remove the "experimental" tag from the
codelist. Reasoning follows:

- this was imported to match the codelist used in commongrants, which
  has a different governance model
- there are neither any current api endpoints nor any theoretical ones
  that people want to implement that would benefit from this
- HSDS' profile mechanism is more appropriate for adding experimental
  features
- the governance model of HSDS means that any experimental API endpoint
  added would need a MAJOR upgrade to remove it
