Set up ORGANIZATION_ADMIN_TOKEN to allow for automatic branch switching

[Ocramius]

Self-release partially succeeded, but we had a failure later in actions run:

That's because ORGANIZATION_ADMIN_TOKEN is not set.

It's obviously a bit risky to add such a variable to the environment, but it should be fine if it's marked as protected (only direct pushes to repository branches can access it).

• Created token with "repo" scope (and a few others for purposes of reading organization data) under laminas-bot account.
• Added laminas-bot user to TSC teams of each of our organizations.
• Created ORGANIZATION_ADMIN_TOKEN secret in each organization, setting the value to the token.
