fix(js): normalize tsconfig include paths correctly in @nx/js/typescript plugin (#30496)

## Current Behavior

The `@nx/js/typescript` plugin infers incorrect inputs for tsconfig
`include` patterns when their last segment doesn't contain a wildcard or
an extension (e.g. `"include": ["src"]`).

## Expected Behavior

The `@nx/js/typescript` plugin should [normalize such `include`
patterns](https://www.typescriptlang.org/tsconfig/#include) and infer
valid inputs.
