We previously held off with updating Octokit to v18 due to
their more noticable issues with typings. This commit updates
us to the latest version in order to take advantage of the new
pagination API (which is also strongly-typed), and to not fall
behind too much over time (Octokit seems to change quite often..)
We work around the problem with the types for `getContent` by just
using a type cast with a TODO (and link to the issue). Similarly we
work around a problem where the Octokit types have an incorrect type
for the name of the labels array in an API response.

Currently the `GitClient` accepts a generic parameter for determining
whether the `githubToken` should be set or not. This worked fine so far
in terms of distinguishing between an authenticated and
non-authenticated git client instance, but if we intend to conditionally
show methods only for authenticated instances, the generic parameter
is not suitable.
This commit splits up the `GitClient` into two classes. One for
the base logic without any authorization, and a second class that
extends the base logic with authentication logic. i.e. the
`AuthenticatedGitClient`. This allows us to have specific methods only
for the authenticated instance. e.g.
* `hasOauthScopes` has been moved to only exist for authenticated
instances.
* the GraphQL functionality within `gitClient.github` is not
accessible for non-authenticated instances. GraphQL API requires
authentication as per Github.
The initial motiviation for this was that we want to throw if
`hasOAuthScopes` is called without the Octokit instance having
a token configured. This should help avoiding issues as within
3b434ed94d
that prevented the caretaker process momentarily.
Additionally, the Git client has moved from `index.ts` to
`git-client.ts` for better discoverability in the codebase.

Creates a singleton class for GitClient rather than relying on creating an instance to
require being passed around throughout its usages.

When multiple target labels are applied to a PR, it should be considered
invalid as our tooling does not support a single PR targetting multiple
