[dotnet][py][java][js]: add `default` as a value for SameSite by navin772 · Pull Request #16129 · SeleniumHQ/selenium

🎫 Ticket compliance analysis 🔶

16128 - Partially compliant

Compliant requirements:

• Add default as a possible value for the SameSite attribute (for dotnet binding)

Non-compliant requirements:

• Implement cookie specification compliance across language bindings (only dotnet shown)
• Support for dotnet, py, java, and js language bindings (only dotnet implementation visible)

Requires further human verification:

• Verification that similar changes are implemented in py, java, and js bindings
• Testing that the Default value works correctly with actual cookie operations
