[skip ci]: Bump keyring from 25.2.1 to 25.3.0 in /src

[dependabot[bot]]

Bumps keyring from 25.2.1 to 25.3.0.

Changelog

Sourced from keyring's changelog.

v25.3.0

Features

• Deprecated support for empty usernames. Now all backends will reject an empty string as input for the 'username' field when setting a password. Later this deprecation will become a more visible user warning and even later an error. If this warning is triggered in your environment, please consider using a static value (even 'username') or comment in the issue and describe the use-case that demands support for empty usernames. (#668)

Looks like keyring is up-to-date now, so this is no longer needed.
