I think the create-payment-credential was not being included in skills list either, and this change updates that. @jlau-stripe was that intentional/is this okay?

[danhill-stripe]

ensure that the build commands update this

[danhill-stripe]

@kreese-stripe didn't we remove this from the other skill?
