ci: Fix JS caching (#270)

Updated CI caching to use a glob for the `node_modules` directories. The
previous wildcard would only search 1 level deep which is not valid for
our setup. This should fix some edge cases that could cause test
failures if the expected package version was installed to the package's
local `node_modules`.

Updated cache action to v4. Added the `save-always` flag to the
`node_modules` cache which should work whenever it's fixed. Ticket for
the flag not working actions/cache#1315.
Without that flag functioning, it acts just like v3 cache
