feat: gather a random gif from the giphy connector

[zimeg]

Type of change

• New sample
• New feature
• Bug fix
• Documentation

Summary

This PR replaces the Find a GIF custom function with the Giphy connector and uses the custom function to format the kudo_message with better formatting.

A few other changes happen too:

• selecting a kudo_vibe is required in the form since something is needed for connector input
• the link trigger defaults to the channel ID it's used in to save this selection
• the custom message formatting function fixes a bug where only the first line of a multiline message was quoted
• the custom message formatting also gathers just the link from the connector response- an example is in tests

Reviewers

Clone the sample:

$ slack create kudo -t slack-samples/deno-give-kudos -b feat-giphy-connector
$ cd kudo
$ slack deploy  # Gather a link trigger

Then test the workflow in a channel. GIF results can be unexpected and prompting the connector is an art. Open to all suggestion here!
