PHP split: replace docker action with manual splitsh-lite + git push

The danharrin/monorepo-split-github-action builds a clone URL as
https://<TOKEN>@github.com which works with classic PATs (token works
as username) but FAILS with GitHub App installation tokens, which per
GitHub docs must be used as https://x-access-token:<TOKEN>@github.com
(token as password, 'x-access-token' as username).

Symptom seen in the failed run after merging v0.0.2:

    fatal: could not read Password for 'https://***@github.com':
    No such device or address

Replacing the action with splitsh-lite v2.0.0 + a manual git push lets
us control the remote URL format. Bonus: splitsh-lite is the same
underlying tool the docker action wraps, and it preserves the full
git history of implementations/php/ as Packagist expects.

Both release.yml (tagged release path) and php-split.yml (master-sync
path) get the same treatment.
