This commit includes all the changes from the CE
branch: 51122-fix-navigating-discussions to port
the changes to EE.

Linking an account allows the external service to sign that user into
GitLab. We need to make users aware of this to reduce the risk of
phishing attacks where users are maliciously tricked into linking
accounts.

We do this by showing a warning and including the group path and the
URL that the user will be redirected to. We also limit the URL to
ASCII characters to avoid homoglyph attacks.

Replace the metrics dashboard graph with
GitLab UI's area chart component

Add information regarding Elasticsearch and deleted documents

Closes #7611
