refactor: extract pull-request workflow to multi jobs & restore cache

[kylemocode]

Why need this change? / Root cause:

• The original unified workflow has been broken down into multiple jobs: build, test, and lint. Both lint and test jobs are designed to run in parallel once the build job completes. This arrangement offers the benefit of maximizing pipeline execution speed in the future when there are other steps that also depend on the results of the build job.
• By utilizing the cache action and using the hash values of yarn.lock and the source code (ts, tsx, js, jsx) as the cache keys, theoretically, both lint and test jobs can make use of the cache created during the build step, eliminating the need to reinstall dependencies.

lint (cache hit)	test (cache hit)

• also update the key in merge pipeline so that it can utilize the cache create from the pull_request pipeline
