The 'Content' section of `m.receipt` is empty

Link to problem area: https://spec.matrix.org/v1.4/client-server-api/#mreceipt

Issue
The "Content" section of m.receipt should feature table(s) describing the fields and types that an m.receipt can be populated with. Instead, it is just a blank space.

Expected behaviour
A rendered set of tables representing the m.receipt schema should be visible.

This might be due to the use of patternProperties?

matrix-spec/data/event-schemas/schema/m.receipt.yaml

Line 12 in bc15d4f

patternProperties:

m.ignored_user_list.yaml uses the same:

matrix-spec/data/event-schemas/schema/m.ignored_user_list.yaml

Line 15 in bc15d4f

patternProperties:

and no "Ignored User" table appears in the spec: https://spec.matrix.org/v1.4/client-server-api/#mignored_user_list

It also appears that patternProperties doesn't exist in OpenAPI 2.0, and was only added in OAI/OpenAPI-Specification#687, so arguably we shouldn't even be using it until we support OpenAPI 3.1 (see #1310 for upgrading to OpenAPI 3.1. Doing so does not magically fix this issue however). That is not how this works.

I'm pretty sure this is a duplicate of the issue I can't find where we discovered that additionalProperties wasn't properly rendered. Whether the field is supported by OpenAPI or not is irrelevant - we define the templates for how these things get rendered.

Do you mean patternProperties? Indeed, I see no mention of the text patternProperties outside of these two OpenAPI definition files, so we presumably have no handling of them in our rendering code.

I mean additionalProperties - I think we fixed it somewhat recently. patternProperties, for all intents and purposes, is effectively the same.

This seems to be a regression from r0.6.1 to v1.1 of the client spec: https://matrix.org/docs/spec/client_server/r0.6.1#m-receipt vs https://spec.matrix.org/v1.1/client-server-api/#events-5
