Add github workflow for automatic API, topic, and component labeling of issues (#36712)

Summary:
Adding a new github workflow script, which will run as part of the existing triage job that is triggered when an issue is  labeled with the "Needs: Triage" label (this typically happens automatically when the issue is created).
This script will add an extensive list of possible labels corresponding to APIs, components, and topics (see the code for the full list).
The motivation for this change is to replace the last bit of meaningful functionality performed by react-native-bot, which will allow us to decommission that bot in favor of using github workflows for all issue and PR automation.

## Changelog:

[INTERNAL] [CHANGED] - Updated API, topic, component labeling on issues to run from a GH workflow rather than an external bot action

Pull Request resolved: https://github.com/facebook/react-native/pull/36712

Test Plan:
For examples of issues being labeled by this new script, see the open issues here: https://github.com/SlyCaptainFlint/react-native/issues
I did not test every possible label, but I tested at least one from each category (API, component, topic), and a combination of one or two of each.
