[6.x] Bump web-auth/webauthn-lib to ^5.3.0 for Laravel Fortify passkeys compatibility

[sstraakenbroek]

What

Updates the web-auth/webauthn-lib constraint in composer.json from ~5.2.0 to ^5.3.0.

Why

Laravel Fortify now ships first-party passkey support via laravel/passkeys, which in turn depends on
laravel/passkeys-server. That package requires:

"web-auth/webauthn-lib": "5.3.x"

Statamic's current constraint ~5.2.0 resolves to >=5.2.0 <5.3.0, which is incompatible with 5.3.x. As a result, installing Statamic alongside
Fortify's passkey feature (or laravel/passkeys-server directly) fails with a Composer dependency resolution error.

References:

• Fortify constraint: https://github.com/laravel/fortify/blob/1.x/composer.json ("laravel/passkeys": "^0.2.0")
• Passkeys-server constraint: https://github.com/laravel/passkeys-server/blob/main/composer.json ("web-auth/webauthn-lib": "5.3.x")

There is more work to be done for this beside just bumping the dependency. We're happy to handle it ourselves. Let us know.
