chore: 🤖 CI/CD Indexation run on event (#240)

## Why?

The "Release by Hash" is to serve the Product team. It's a custom
process. When successful, it merges a subset of develop into main
branch. We call this a "Release to production". For some reason, since
this was introduced, the CI/CD Search Indexer stopped working, e.g. "on:
push". The issue was reported to GitHub and seems that it has a
limitation that prevents it from triggering "on: push" with the right
context. See
[here](https://github.com/orgs/community/discussions/139698)

## How?

- Update workflows to trigger event by a name in post release success,
and listen to event name in ci/cd of search
- Updated documentation

## Tickets?

-

## Contribution checklist?

- [x] The commit messages are detailed
- [x] The `build` command runs locally
- [ ] Assets or static content are linked and stored in the project
- [ ] Document filename is named after the slug
- [ ] You've reviewed spelling using a grammar checker
- [ ] For documentation, guides or references, you've tested the
commands and steps
- [ ] You've done enough research before writing

## Security checklist?

- [ ] Sensitive data has been identified and is being protected properly
- [ ] Injection has been prevented (parameterized queries, no eval or
system calls)
- [ ] The Components are escaping output (to prevent XSS)

## References?

Optionally, provide references such as links
