automate release for cocoapods via github actions

[fumito-ito]

This PR automates the publishing to CocoaPods using GitHub Actions. This action will attempt to release to CocoaPods whenever a new release is created, using the release’s tag_name as the version. Please note that the environment variable COCOAPODS_TRUNK_TOKEN must be specified.

Hi @groue . It’s been a while. To automate the publishing to CocoaPods with this change, I need the COCOAPODS_TRUNK_TOKEN. If possible, could you register the COCOAPODS_TRUNK_TOKEN in this repository’s Secrets? I would greatly appreciate it if that’s feasible.

Hi @fumito-ito :-)

Wouldn't the token give access to all the CocoaPods I maintain, not only GRMustache.swift?

I'd rather add the email of your choice, if this is OK for you.

@groue You’re absolutely right. Instead of registering the token, it seems more appropriate to add my email address as an owner. Could I kindly ask you to add [email protected]? I appreciate your help.

Done! pod trunk add-owner GRMustache.swift [email protected]

Please tell me if I can help more.
