[BUG] payload of type date shows validation error

[sam0r040]

Describe the bug.

AsyncAPI studio shows an error for data type date when YAML is used while data type datetime works fine.

Interestingly enough, if the date string is wrapped in double quotes, the validation error goes away.

Expected behavior

Validation passes for the provided yaml.

Hi @sam0r040!

The issue comes with the library we use for parsing YAML, which is js-yaml.
There are several issues opened on their repository talking about this. For example: nodeca/js-yaml#161

The summary is that, whenever that parser finds a field that is not an explicit string (without quotes), it fallbacks to some schemas. The default one is called "Core" , and is supposed to be based on YAML spec, so whenever it finds a value with the format of date, it transforms it into a datetime. Means, it transforms from 2015-07-20 to 2015-07-20T00:00:00.000Z.

As the first and quick solution, I encourage all those values to be enclosed with quotes.
However, I tested their recommendation of using other fallback schemas, in particular the JSON Schema one and the parser is able to parse properly without those errors.

loadedObj = yaml.load(asyncapi, { schema: yaml.JSON_SCHEMA });

All tests are passing, but not 100% sure if adding that could break other documents, so not sure if this possible fix would become a breaking change 🤔

This bug gets fixed for both studio and studio-next by changes in packages:

• @stoplight/spectral-core
  https://github.com/stoplightio/spectral/blob/develop/packages/core/package.json#L46

  - "ajv": "^8.6.0",
  + "ajv": "^8.17.1",

  stoplightio/spectral@4b4b46e
  (changes in other packages are required to build spectral)

• @asyncapi/parser
  https://github.com/asyncapi/parser-js/blob/master/packages/parser/package.json#L57

  - "ajv": "^8.11.0",
  + "ajv": "^8.17.1",

  4a9fd5c

Compiled directories used:

• ./packages/parser/cjs for studio.
• ./packages/parser/esm for studio-next.

All tests both in @stoplight/spectral-core and @asyncapi/parser pass with these changes.

Should I create PRs or might there be some hidden caveats?
