* feat(manager/dockerfile): extract `apk add` packages from `RUN` instructions
As noted in #43711, users pin APK packages in their Dockerfiles and want
Renovate to update them, which so far has needed a custom manager[0].
Now that we have the `apk` datasource, we can extract these ourselves,
and parse the `RUN` instruction more effectively than a regex can.
We can do this by:
- extracting `apk add` dependencies when processing a `Dockerfile`
- ignoring common flags to `apk` before we extract the dependency names,
which wasn't straightforward with a Custom Manager
- ignoring i.e. `--virtual .build-deps`
- handle example cases from [0] and other usages i.e. with a comment in
between lines
- ensure that `final` doesn't run against the final `apk` install
- removing the docs for how to do this with a Custom Manager, as that
complexity is no longer needed
- skipping `unspecified-version` and `contains-variable`
We inform the user that they will need to override the `registryUrls`,
as we already have a default on the `apk` datasource and can't override
it in a straightforward means.

Find the command by name wherever it sits in the tokens, rather than
skipping an allowlist of shell keywords and variable assignments, so that
a wrapper program like `sudo`, `chroot /mnt` or `timeout 30` is handled
too.
