Should fix messed up import suggestions and simplifies all tsconfigs
through inheritance.
One main issue was that packages were inheriting `baseURL: "."` from the
root tsconfig. This caused incorrect import suggestions that start with
"packages/...".
This PR ensures that packages do not inherit this baseURL: "." property,
while ensuring the root, non-inherited tsconfig still keeps it to get
tests to work (the importMap needs it)
BREAKING CHANGE: Rename `@payloadcms/plugin-cloud` to
`@payloadcms/payload-cloud`. Anyone using the existing plugin will need
to switch to using the new package.
## Why?
Since v3 will be using _fixed versioning_, all versions of `^3` must be
available. Unfortunately, the `@payloadcms/plugin-cloud` version has
already breached that version number. Renaming will allow it to be on
the same version as other monorepo packages.
Additionally, the name `plugin-cloud` is quite ambiguous and sometimes
is confused with `plugin-cloud-storage`, so using `payload-cloud` feels
like a good move to make this more evident.
