Properties should be lowercase

[ioggstream]

I expect

Properties to be lowercase. See https://docs.italia.it/italia/piano-triennale-ict/lg-modellointeroperabilita-docs/it/bozza/doc/profili-di-interazione/regole-comuni-rest-soap.html#formato-dei-dati

Instead

https://github.com/italia/pc-web-validator/blob/df0c77efb8497d39eb1b2db9e55613e34360fcf8/api_spec_oa3.yml#L88

You can just edit the yml file

as per errors.go file interested struct since no json struct tag is specified on any field

publiccode-validator/src/errors.go

Lines 18 to 21 in 66e39c3

	type ErrorInvalidValue struct {
	Key string
	Reason string
	}

will automatically use lowercase field names "key" and "reason". So just change the spec without issues.

They are still there to do not break the backward compatibility, but they will be removed on next release.
