WIP: Trigger build workflow on lifecycle-release dispatch event and update builder.toml lifecycle version

[glokta1]

Ensures sample builders are up-to-date with the lifecycle. See https://github.com/buildpacks/lifecycle/issues/801

Will update this PR with the script to update builder.toml files in a bit. I suspect I won't have write permissions to modify files though so I'm a little confused on how to test it...any pointers? :sweat_smile:. I'm new to testing these workflows

I like this idea. I need to get my head around GH triggers before I approve it.

There may be a better way to do it, feedback is welcome :)
