feat: Support globs and arrays of paths/globs for the `schema` option and `generate-schema` command arguments

[!NOTE] Marked as draft since it's kind of a proposal, due to it being requested multiple times. Coordination with graphqlsp is also needed. We may also want to use this opportunity to work on error handling (?) The risk of errors increases by a lot when we accept multiple SDL files, that have potentially not been processed by other tools.

Summary

This has been requested multiple times now, and I thought I'd take a stab at implementing it.

When applied, this PR allows the schema option to accept arrays of paths, arrays of globs, and globs. This means that multiple SDL files can now be merged into a single one with the generate-schema command and that the SDL loader will discover multiple files.

This has been implemented using ts.sys.readDirectory, which should already support this pretty comprehensively.

When multiple .json files are discovered, an error is thrown.

The risk of errors increases by a lot when we accept multiple SDL files, that have potentially not been processed by other tools. This is because they might have been hand-written and not validated by any other tool. I haven't figured out yet what to do about this, especially since GraphQLSP/TSServer cannot output global errors. I'm currently thinking, we can only merge this if we have a strategy for surfacing global errors in graphqlsp.

Set of changes

DANGER: The loadFromSDL config signature has changed to accept a rootPath
loadFromSDL now uses ts.sys.readDirectory to discover multiple schema files
When loadFromSDL is used with a single JSON file nothing changes, otherwise, if multiple files are discovered and one is a JSON file, an error is thrown
generate-schema command now accepts multiple input strings
