[WIP] ci: unify dependency profiles across PR and nightly runs

[galargh]

This PR expands the version combinations we test foc-devnet with.

The general setup is to test in 3 modes/profiles:

• default: pinned version numbers of all dependencies (in this context, that means: Lotus, Curio, filecoin-services, Synapse SDK, and filecoin-pin)
• stability: latest releases of the dependencies (used in nightly builds)
• frontier: latest commits of the dependencies (used in nightly builds)

To track all of this, I introduce a JSON dependency manifest (ci/dependency-profiles.json) which describes these profiles: what version to use, where to get it from (git vs npm), etc.

I also fixed the dependency-version-dependent cache setup and updated the test scenarios to use the dependencies tracked by the manifest.

Testing

• Run the test scenarios on a PR on this branch (blocked on main being broken - [TEST] Testing pull request builds #129)
• Run the nightly tests from this branch (blocked on nightlies being broken - FOC Devnet scenarios run report (frontier) #117)

TODO

• When installing filecoin-pin, pin multiformats to the version that synapse-sdk accepts.
