Add rel=me to user's website link

See merge request gitlab-org/gitlab-ce!24089

rel=me links allow cross-linking of user's identities. This behavior is
used by software to determine if user controls profiles on two different
sites. For example Mastodon uses it to display verified badge on links.

Both Twitter and GitHub automatically add rel=me to links added to
users' profiles.

Fix deprecation: Using positional arguments in integration tests

See merge request gitlab-org/gitlab-ce!24110

Webhook URLs were recently encrypted in the database via
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/21645, and as a
result they are no longer exported. When an exported project with
Webhooks is imported, the project import service will fail with
`URI::InvalidURIError: bad URI(is not URI?)` due to a blank URL.
We avoid this by disabling the export/import of Webhooks in
the first place.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/53513

Prefer to use after_transition

This will allow developers to run `bundle install` on both directories

up the possibility of improved caching as mentioned in
https://gitlab.com/gitlab-org/gitlab-ce/issues/55843.
