Docs: fix errors on infra page, build ordered lists

Closes #217144

See merge request gitlab-org/gitlab!32694

The changes recently merged to the infrastructure page did not
completely incorporate the edits from the technical writer. The (long)
example YAML file was included twice, and the numbered list
restarted at 1 in a few places because of code blocks that weren't
fully indented.

This MR adds in consistent line breaks to the page, rewrites several
tiny subheadings to be a single list of numbered steps, and fixes
the problem with the doubled copy of the code example.

Step 2 - Extract sidebar_nav component from collapsible_panel

See merge request gitlab-org/gitlab!32465

Previously it was possible for the only owner with SSO access to leave
the group. This would leave the group without any owners that could
access the group or turn off SSO Enforcement, as none of them would pass
the SSO Enforcement to gain access. Additionally Group Managed Accounts
means that attempting to re-join the group would result in a sign up
form being presented and requiring a different email, preventing a the
owner from re-gaining access.

See merge request gitlab-org/gitlab!29270

We want to have the UI for group import as well as the existing API.
Create the controller endpoints required to support the group import UI.

For now, this process will be identical to the existing API
functionality and will be visually the same as the existing project
import.

Log bytes read from / written to Redis

See merge request gitlab-org/gitlab!31352

This adds instrumentation for the number of bytes written to and read
from Redis. To avoid having to monkey-patch multiple methods of
Redis::Client, this change introduces a custom Redis driver which
inherits from the default Redis::Connection::Ruby driver.

Counts include the size of the commands (GET, SET etc.), but exclude
the size overhead of Redis serialization (type, length prefix,
trailing \r\n).
