build: invalidate circleci cache to prune unused nested node modules (#25512)

Yarn 1.x has a bug where it keeps nested unused node modules and doesn't
delete them automatically. This throws off Bazel in some scenarios when
the lock file is updated. This commit invalidates the cache to get a
fresh clean node modules cache without any unused nested directories.

(cherry picked from commit 7859dbb)

 # We want to invalidate the cache if the postinstall patches change. In order to apply new
 # patches, a clean version of the node modules is needed. Additionally, we invalidate the cache
 # if the Bazel version changes. We do this because otherwise the `bazelisk` cache folder will
 # contain all previously used versions and ultimately cause the cache restoring to be slower.
