Add github dispatch for operator sync workflow

[maroroman]

Prerequisite for: opendatahub-io/opendatahub-operator#205

Description

This workflow sends a dispatch whenever a pull request is merged that modifies the crd folder of the dashboard repository. The operator has a workflow that then copies these changes automatically.

How Has This Been Tested?

This PR was tested using https://github.com/nektos/act to locally verify that the workflow is sending the dispatch correctly.

To test this in real conditions, a fork of the operator and dashboard is required:

1. Create a pull request in the odh-dashboard fork that changes a file in /manifests/crd folder
2. Merge the PR into the main branch of the fork
3. Verify that the action has been triggered
4. Verify dispatch reached opendatahub-operator fork sync workflow and has triggered it.

Test Impact

No tests are done for github workflows (afaik)

Request review criteria:

• The commits have meaningful messages (squashes happen on merge by the bot).
• Included any necessary screenshots or gifs if it was a UI change.
• Included tags to the UX team if it was a UI/UX change.
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has manually tested the changes and verified that the changes work
• The developer has added tests or explained why testing cannot be added (unit tests & storybook for related changes)

Just a sidenote, I am still trying to make this work with my forks, but locally the command is fine, so it should work in real conditions as long as the trigger is correct.

How do we test this @maroroman ? @VaishnaviHire / @LaVLaS

@andrewballantyne I verified that the dispatch works and is received by the operator (my fork of it) through the utility I mentioned in the test description.

To test the trigger it could be used as well or we can use some forks through the steps I wrote. I had trouble with those forks but that trigger is (as far as I know) exactly as the documentation states, so it should work :D

Can we have more context, this is handle by the deployer downstream, are we moving away from that these files? Is this only targeted to upstream? Just to make sure we then disable it downstream.

Based on a conversation with @VaishnaviHire this should only be targeted at upstream.

@LaVLaS or @VaishnaviHire please approve this before we will merge it.

This is a github action and I don't mind the inclusion in the dashboard repo, but this is not for our dashboard effort so I need someone from the manifests team to approve this functionality.

The checkout action works, I've tested it locally to other repo (didn't want to break anything in the operator repo) and it's working.

@LaVLaS @VaishnaviHire if you can validate and greenlight this we can review it and merge it.

Sorry for the delay. Yes this looks good, we can merge it.
