Move chainspecs to a dedicated directory

[ales-otf]

Description

This PR moves chain spec files into a dedicated directory chainspecs.

It also fixes build_all_chainspecs.sh script by preventing genesis rewrites in the plain specs. And extends it to build devnet specs as well.

The bootnode address for testnet is changed to /dns/bootnode.test.chain.opentensor.ai/tcp/30333/p2p/12D3KooWEKUzXbgbJzCnAGcCLFwcEbDBp9ixa3aVVgJ5smiX1fSJ (requested by prop_physics)

Additional Notes

Warning

As the script previously didn't handle keeping of genesis for plain specs, the plain specs genesis for finney and testfinney don't match the one in the raw specs.

looks good to me. @rajkaramchedu the spec file folder is changed. we need update the doc https://docs.bittensor.com/subtensor-nodes.

I haven't looked at the code of this scripts/localnet.sh in detail, but I assume this script is not impacted with this PR? cc @galina-opentensor

It's not. scripts/localnet.sh first builds the chainspec file inside scripts/specs and then uses this file (actually, for localnet we can omit doing it and just specify the chainspec name).
