chore: add eslint test script to package.json (TanStack#8979)

* chore: add eslint test script to package.json

Add a new script "test:eslint" to run eslint on the src directory, improving code quality checks during development.

* fix(nx): ensure test eslint depends on build for plugin workspace

Added nx configuration to make test:eslint target depend on the build target of its dependencies, ensuring the eslint plugin workspace is built before running tests.
