feat: Allow sourcing plain files (not just binaries) and remove Paseo chain specs generator in favor of chain specs

[tsenovilla]

Closes:

• feat: Stop using chain spec generator for Paseo #773

By:

• Allowing source plain files, not just binaries. This extends the cache concept of pop and might be used by other features in the future.
• Using the released chain specs for Paseo instead of the former chain spec generator. This implies that in the future we can get rid of this repo as well: https://github.com/r0gue-io/paseo-runtimes (when we stop giving support to some old pop versions).

[tsenovilla]

Some IDs aren't correct on Paseo last release's chain specs. Namely BridgeHub, People, Collectives and Coretime have a wrong ID and cannot be used to launch a network using pop up yet.

This is already addressed here and will be included in next release, so just be aware of it til that release is out.

This also will make the CI fails cause this test cannot pass until Paseo 2.0.2 is out. That's why I'm directly using 2.0.2 as fallback even if it's not out yet.

@AlexD10S mind to add copilot as a reviewer? Don't know why I can't 😢

Pull request overview

This PR extends the caching and sourcing capabilities of pop to support plain files (not just binaries) and migrates Paseo chain specifications from using a generator to pre-built chain spec files hosted in the paseo-network/runtimes repository.

Key changes:

• Introduces ArchiveType enum (Binary | File) to differentiate between executable binaries and plain files
• Renames Binary to SourcedArchive to better reflect that it can now handle both binaries and files
• Adds chain_spec_file() function to source chain spec JSON files directly from releases
• Updates Paseo runtime sourcing from r0gue-io/paseo-runtimes (chain spec generator) to paseo-network/runtimes (pre-built specs) with fallback version v2.0.2
• Adapts path construction logic to handle file extensions when versioning (e.g., paseo-local-v2.0.2.json)
