Post commit hook doesn't show up

What steps will reproduce the problem?

Documentation claims there are currently six types of hook script available, including Post-commit hook.

However, I'm using the latest TortoiseGit (version 2.5), I only have 5 hooks, missing Post-commit hook. See the screenshot.

What is the expected output? What do you see instead?

I expect to see Post-commit hook. I actually don't see Post-commit hook.

What version of TortoiseGit and Git are you using? On what operating system?

TortoiseGit version 2.5, Git version 2.15.1.

I'm using Windows 10.
