Support PATCH requests in dev tools console

[rseldner]

Describe the feature:
Support PATCH requests in dev tools console for Kibana APIs

Describe a specific use case for the feature:
PATCH requests are not supported in Kibana Dev Tools Console.

Calls to the API endpoints require different operations. To interact with the Kibana APIs, use the following operations:

• GET - Fetches the information.
• POST - Adds new information.
• PUT - Updates the existing information.
• DELETE - Removes the information.

Source:https://www.elastic.co/guide/en/kibana/8.7/api.html#api-calls

There are a some Kibana APIs for Security and App Search endpoints that support PATCH.
It would be helpful to add PATCH support as their PUT equivalents can be cumbersome/tedious to build.

EXAMPLES:

(Security) Update Rule - https://www.elastic.co/guide/en/security/8.7/rules-api-update.html

Equivalent request body comparison to update a rule's max_signals. This one is of particular interest as it cannot be changed via the UI, even for custom rules.

PATCH (much easier but would require an external REST client)

There are a few alerting HTTP endpoints that use PATCH as well - though it appears they are all internal (not considered API) ATM.
