Write to console instead of file, to leverage GHA native logs

[aldenquimby]

Background

• I recently started using this action and noticed the run logs don't have meaningful output:

• To see the logs, I need to navigate back to a run summary, download an artifact, unzip, and view:

• Afterwards, I need to delete the zip + txt file from my local machine

Proposal

• This PR proposes inlining the logs instead, so they are immediately useful and searchable within the native GHA log UI:

• Added benefit of removing a dependency on the upload-artifacts action

Did you have a chance to test this out? I have a feeling that bash command output is not copied to GHA output

@duskpoet yes I tested this by switching my project to use aldenquimby/create-branch-action@alden-test-output and it worked. See the screenshot at the bottom of the PR description for what it looks like
