fix: programmatic validation removes previous errors if all data is now valid

[raing3]

Reasons for making this change

Programatic validation doesn't clear the errors if the form has been changed from being invalid -> valid. This results in stale errors remaining.

Reproduction steps:

1. With the following example form: https://rjsf-team.github.io/react-jsonschema-form/#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
2. Click the Programmatic "Validate" button, an error indicating name is required should appear.
3. Fill in the name field.
4. Click the Programmatic "Validate" button again.

Expected: The error should disappear after clearing invalid data and re-validating.
Actual: The error remains after clearing invalid data and re-validating.

Workaround:

Pass additional props when rendering Form so the state will still be updated if there are no errors:

        extraErrors={{}}
        extraErrorsBlockSubmit={true}
