feat(yarn): add workspace as dependencies and use `workspace` relationship for them

[DmitriyLewen]

Description

We currently don't expose workspace as separate packages (only define direct and indirect dependencies on them).

After #7889 we can add them with the workspace relationship.

Required changes:

• detect workspace packages from path/to/workspace/package.json files.
• use workspace relationship for these packages
• add relationships between workspaces and direct packages of workspaces.
• ??? detect project id from root package.json file to add root package (@knqyf263 wdyt?) and add workspaces as dependencies of root package

??? detect project id from root package.json file to add root package (@knqyf263 wdyt?) and add workspaces as dependencies of root package

Yes, we should do that.
