Fix pf tag parent (#1930)

fixes #1926

Correctly parent master to the last pf release in order for go to
increment pre-release versions correctly.

This works: pulumi/pulumi-tls#503 - this is the
hash from this PR.

This is before this PR:
pulumi/pulumi-tls@c039dbf#diff-cd249c062d77b4d6a5621756423850d0708ffbe4aae554ce33cdc5b908b0ee39

Notice that the pf pre-release version was
`v0.33.1-0.20240503212316-40b530845390` which, when competing with
`v0.34.0` resolved to `v0.34.0`, even though
`v0.33.1-0.20240503212316-40b530845390` is newer.

Now the version is correctly labeled as post-0.34.0:
`v0.34.1-0.20240506185132-7e489cef7052`
