Obtain fellows from People Chain

[Bullrich]

• Migrated the chain from polkadot to People Chain.
  • Resolves Update to use People Chain #29 and resolves Update CI for Polkadot People Chain polkadot-fellows/runtimes#394
• Updated PAPI to latest (it now has a .papi directory).
  • Removed slim node docker image and bundled everything together
    • Polkadot-API depends on some dependencies that ncc is not bundling together so we need to keep the node_modules (like @polkadot-api/metadata-compatibility)
• Updated to version 1.2.0

@mutantcornholio I think we will have to remove the immutable from the installation step as the "files" inside the papi directory uses the workspace as part of the hash:

➤ YN0028: - resolution: "@polkadot-api/descriptors@file:.papi/descriptors#.papi/descriptors::hash=8e5d63&locator=get-fellows-action%40workspace%3A."
➤ YN0028: + resolution: "@polkadot-api/descriptors@file:.papi/descriptors#.papi/descriptors::hash=dfa29b&locator=get-fellows-action%40workspace%3A."
➤ YN0028: - checksum: 10c0/1d1a20c19957b0ebebcdea59306a0d2beed23324d0d11d061cb04a3725bee279771d7a019d7914eee9b6304ba40403a1d0cb0e379cab1c1f7b3c86886a529d79

@Bullrich try removing papi from postinstall and invoke it as a separate step

I tried that with 9aaa35c but doesn't seem to be working
