Modify Workflow to Build Signer Releases

[BowTiedDevOps]

Make the required modifications in order to be able to release stacks-node and stacks-signer separately.

Changes:

• Source Dockerfiles: The CMD instruction now only runs the signer if it is a signer release, otherwise the node.
• Workflow dispatch input has been removed, the tag is now parsed from the branch name it's being run against.
• Use composite action that checks if the branch name matches the pattern of a release or not.
• If it is a release run, build the binaries of the specific release type (only stacks-signer if it is a signer release, otherwise all binaries), then publish the release.
• Publish to stacks-signer docker repository if it is a signer release, otherwise to default repository (stacks-core in this case) as well as the legacy stacks-blockchain.

How is the release built now?

• When a release is ready to be created and published, the CI Workflow will have to be run via the workflow_dispatch event against the release branch.

Release branch patterns:

• release/x.x.x.x.x(-rcx) - A node release branch, where x are numbers, and -rcx is optional.
• release/signer-x.x.x.x.x.x(-rcx) - A signer release branch, where x are numbers, and -rcx is optional.

Workflow example runs (test failures are unaffected by these changes):

• Node Release: https://github.com/BowTiedDevOps/stacks-core/actions/runs/9912429239
• Signer Release: https://github.com/BowTiedDevOps/stacks-core/actions/runs/9912430933
• No Release (CI Workflow run against master branch of stacks-core): https://github.com/BowTiedDevOps/stacks-core/actions/runs/9910596033
• No Release (CI Workflow run against develop branch of stacks-core): https://github.com/BowTiedDevOps/stacks-core/actions/runs/9910597101

Releases built by this workflow:

• Node: https://github.com/BowTiedDevOps/stacks-core/releases/tag/2.8.0.0.0
• Signer: https://github.com/BowTiedDevOps/stacks-core/releases/tag/signer-2.8.0.0.0.1
• Full Release Page: https://github.com/BowTiedDevOps/stacks-core/releases

Docker images:

• stacks-blockchain repository: https://hub.docker.com/repository/docker/bowtieddevops/stacks-blockchain/general
• stacks-core repository: https://hub.docker.com/repository/docker/bowtieddevops/stacks-core/general
• stacks-signer repository: https://hub.docker.com/repository/docker/bowtieddevops/stacks-signer/general

The PR was marked as draft because there are still documentation changes in progress.

Needs documentation updates for release process in the README

[wileyj]

my bad - my push yesterday failed because i didn't rebase first.
added the first-pass of signer docs @jferrant @hstove would appreciate if you could let me know if i'm on the right track there.

i think for the stacks-core release docs, i'm going to make as few edits as i can so it's still correct, and address missing/changed items in a different PR so this isn't blocking upcoming deadlines.

Bare minimum was updated - it's not entirely correct, but it's close enough to open this for review.

I'll address the larger docs changes in a separate PR.

Overall looks good! Left a few suggestions, but nothing important enough that should be considered blocking.
