ci: add updated release process for ITS

[apolikamixitos]

What:

Add a new process to release Interchain Token Service packages and contracts.

pre-release Workflow:

Ensures that the changes introduced are ready to get published, as the name suggests, it's a pre-release step that creates a PR that could be double-checked before proceeding with publishing a release.

release Workflow:

This workflow ensures:

• The new versions of the package @axelar-network/interchain-token-service are published to npm.

• New releases/tags are published on Github:
  • Includes the source code of the package.
  • The package-related assets (contracts ABIs associated with its corresponding package version).

• Artifacts being published to R2 as a secondary backup source and distribution channel:

release-snapshot Workflow:

• It's used mainly for nightly || ad-hoc build to trigger testing purposes, they aren't supposed to be used for production environments.

Notes:

Some requisites need to take place before merging the PR:

• Ensure that the proper vars and secrets are set up in the repository config.
