ci: inline beta release jobs to fix PyPI trusted publishing

[vdusek]

Summary

PyPI's Trusted Publishing rejects OIDC tokens issued from reusable workflows:

The claims in this token suggest that the calling workflow is a reusable workflow. Reusable workflows are not currently supported by PyPI's Trusted Publishing.

on_master.yaml was invoking manual_release_beta.yaml via uses:, which made the OIDC token reflect a reusable workflow call. The same fix has already been applied in apify/apify-shared-python#63 and apify/crawlee-python#1875.

Changes

• on_master.yaml: inline the four beta release jobs (release_prepare, changelog_update, pypi_publish, doc_release_post_publish) directly, instead of calling manual_release_beta.yaml as a reusable workflow.
• manual_release_beta.yaml: remove the workflow_call trigger (no longer invoked from another workflow) and add a comment explaining why the duplication exists.
• Drop the unused tag_name output from release_prepare in both files.

Follow-up

The PyPI Trusted Publisher for apify is currently configured for manual_release_beta.yaml. After this is merged, an entry for on_master.yaml needs to be added on PyPI so the automatic beta release passes verification.
