"footer.logo.alt" is not allowed to be empty

🐛 Bug Report

This is exactly the same issue as #3350, but this time in the footer config instead of the navbar config.

When I use an empty string for footer.logo.alt in my config, I get the following validation error:

ValidationError: "footer.logo.alt" is not allowed to be empty

Have you read the Contributing Guidelines on issues?

Yes

To Reproduce

1. Create a new Docusarus v2 project.
2. Set footer.logo.alt in themeConfig in docusaurus.config.js to ''.
3. Run npm start.

Expected behavior

The website to start just fine with the footer logo having an empty alt="" attribute.

Actual Behavior

The site doesn't compile and an error is shown in the terminal output:

A validation error occured.
The validation system was added recently to Docusaurus as an attempt to avoid user configuration errors.
We may have made some mistakes.
If you think your configuration is valid and should keep working, please open a bug report.
