[Bug?]: JSON Schema errors in 4.11.0

[joshkel]

Self-service

• I'd be willing to implement a fix

Describe the bug

Starting with Yarn 4.11.0, the JSON Schema that it publishes to validate .yarnrc.yml files results in errors in VS Code:

Schema 'Yarn Config (.yarnrc.yml) - Yarnrc configuration files (yarnrc.json)' is not valid:
/properties/httpTimeout/type : must be equal to one of the allowed values
/properties/httpTimeout/type : must be array
/properties/httpTimeout/type : must match a schema in anyOfYAML(768)

To reproduce

Open a .yarnrc.yml file in VS Code.
