Send nostr note when PR is merged

[anurag-l1nt]

This PR includes the configuration and necessary scripts for a GitHub Action that posts a note on Nostr when a PR is merged. The note will include the user who created the PR (being mentioned with their Nostr pubkey if one is configured in the "socials" section of their profile), the title of the PR, and a link to it

For the execution to work correctly, the following variables and secrets need to be set in the repository:

• NOSTR_RELAYS: Environment variable with a list of relays where the note will be sent, separated by commas. For example: wss://nos.lol,wss://relay.damus.io
• NOSTR_PRIVATE_KEY: Secret containing the private key in hexadecimal format that will be used to publish the note.

I must mention @laanwj , whose code from their ghi repository I partially used for the scripts.

I remember there are some bots that post NIPs changes.

Not the way I’ve implemented it. GitHub Actions run within a specific repository, and this particular one is triggered upon merging a PR. To achieve this in another repository, a scheduled action would be needed that runs at regular intervals and periodically queries the GitHub API to check for changes. It would be a different and more complex approach.

If the admins of this repo have no objections to adding the GitHub Action, I believe it’s a simpler and cleaner solution.

I knew there were bots that sent notes to Nostr about PR merges for BIPs, Bitcoin Core, and others, but I wasn’t aware of any for NIPs. At the time, I had searched and couldn’t find any (which doesn’t mean they don’t exist).
