Add a section of examples to code review docs

Closes #64194

See merge request gitlab-org/gitlab-ce!30825

We have a fairly good guide to Code Reviews, but can be improved
by adding a few examples of what a good code review looks like
at GitLab, specifically ones where there is a bit of back and
forth, "nit-picking," etc. This would:

+ help set expectations of newly hired engineers around what our
process looks like when it is functioning what level of scrutiny
their code will be under

+ how we have technical conversations

+ show by example how after you're done crafting a solution, there
can still be extra work done either tidying up code and/or managing
the communication and conversations about your proposed MR

Vue-i18n: Autofix additional i18n lints for vue files

Autofixes additional linting errors
found in vue files.

Refactor usage data counters specs

See merge request gitlab-org/gitlab-ce!31013

This was shown in specs but surely this will be happening in application
code as well if this method is passes a frozen string.

We were also trying to force_encode a OmniAuth::AuthHash which had the
very confusing behaviour of returning nil when it was sent a method that
it did not define. Fix that by only force_encoding a String.

[CE] Create serializer for Jira API JSON payload

See merge request gitlab-org/gitlab-ce!31139

Docker Distribution v2.7.0 shipped with OCI support, but our container
registry client was not updated to handle the manifest format in the
HTTP `Accept` header.  As a result, API calls to retrieve a manifest
would return with an error, "OCI manifest found, but accept header does
not support OCI manifests". This would result in blank fields in the
container registry page and prevent tags from being deleted.

To fix this, we just need to add
`application/vnd.oci.image.manifest.v1+json` to the `Accept` header and
configure Faraday to parse the response as JSON. The response structure
is the same as the standard Docker Distribution V2 manifest.
