chore(release-blogs): fix a few issues

[avivkeller]

Fixes the following with the release blog post generator:

1. Set the working directory, as otherwise it'll use turbo (and not correctly pass the $VERSION argument
2. Apparently, we need to pass GITHUB_TOKEN explicitly to this action (https://github.com/gr2m/create-or-update-pull-request-action/blob/master/index.js#L15), and it needs a bit more permissions
3. In nodejs/node, the version will be passed as vX.Y.Z format, and the script is currently only equipped to handle X.Y.Z format
4. We want the script to throw an error when it fails, as to disrupt the workflow run.

Sorry that this ended up being two PRs! You can't test a workflow_dispatch trigger before it's merged into the main branch.

Successful Run: https://github.com/nodejs/nodejs.org/actions/runs/18730461924
Example PR: #8260 (The content of this PR looks like it doesn't do anything, but it generated a release post identical to that of main, hence why the file diff didn't incldue it)

This PR fixes several issues in the release blog post generator workflow and script to properly handle version arguments and error reporting.

Key Changes:

• Updated argument parsing to use parseArgs instead of manual process.argv manipulation

@avivkeller I wanted to share https://github.com/github/local-action - I recently discovered this and found it useful - it sorta depends on how a workflow is constructed, but it is more lightweight than https://github.com/nektos/act
