Document to use `name: review/$CI_COMMIT_REF_SLUG` instead of `review/$CI_COMMIT_REF_NAME` for review apps
Problem
Pointed out by the comment by @hfyngvason.
Currently, our documentation recommends to use environment: review/$CI_COMMIT_REF_NAME
for configuring review apps, however, this sometimes causes an environment creation error by an invalid name. Users should use $CI_COMMIT_REF_SLUG
instead, that automatically sanitizes/normalizes the invalid invalid characters.
Proposal
Replace environment: review/$CI_COMMIT_REF_NAME
by environment: review/$CI_COMMIT_REF_SLUG
.
