fix: make action compatible with @changesets/cli@2.27.8

• Closes Fix release workflow fuels-ts#3226

A recent dependabot patch bump of the @changesets/cli package in FuelLabs/fuels-ts#3173 caused the subsequent release workflow of fuels to silently fail when creating a GitHub release. This happened because the silently failing logic depended on the published output of this action to be true, but it was false even though the publish to the npm registry happened.

Upon inspection, I found the problem to be the PR changesets/changesets#1417 which was released in @changesets/cli@2.27.8, which caused the outputted logs to contain coloring escape codes whereas previously they weren't there (uncolored and successful run, colored and silently failing run). Because the published variable's setting depended on parsing of the outputs of the pnpm changeset cli run, and these outputs have become intertwined with escape codes, the parsing failed even though the publishing itself was successful.

This PR updates the regex with which the parsing is done, so that now the necessary info is extract from another place in the logs which remained unchanged after the version bump. Previously it was taking the published package names from:

🦋  info Publishing "@fuel-ts/abi-coder" at "0.94.6"
🦋  info Publishing "@fuel-ts/abi-typegen" at "0.94.6"
...

Now it's taking them from:

🦋  success packages published successfully:
🦋  @fuel-ts/abi-coder@0.94.6
🦋  @fuel-ts/abi-typegen@0.94.6
...

Thus, this regex is now compatible with both the previous and new version of @changesets/cli.
