fix(install-browsers): install cypress if detected

[barbados-clemens]

• run playwright and cypress install in browser step
• cache playwright and cypress binary caches in CI

NOTE: playwright actually recommends not caching the binaries as it's just faster to download anyways? and in my testing it just redownloads anyways ignoring the previous cached version, while cypress skips installing. unsure how we feel about that?

Second note: cache paths are from the workspace root i.e. ~/workspace, but binaries are installed at ~/.cache. This means we need to path up and over to the .cache directory.

Third note: what is the correct key here? ideally I could pass in the cypress/playwright version but can only use globs and hard coded values. for now it's the lock files + "browser" key.
