This new `base-authoring-package` captures all the settings, which
turns of potentially fatal checks, in one place. This new package is
then used as a base for all the docs-watch related packages, rather
than dotting the settings in a variety of different packages. This also
has the benefit that the standard configuration for doc-gen is fatal
on failed checks by default.
PR Close#40479
Checks that cause the doc-gen to fail were already disabled in `docs-watch`
for the doc-gen that runs when a file is changed.
Now these checks are also disabled for the initial doc-gen run.

This helps to ensure that the full docs have been
generated before we begin watching.
You can disable this by providing the `--watch-only`
flag. E.g. `yarn docs-watch -- --watch-only`.
