51Degrees RTD submodule: optimise ORTB2 enrichment speed

[jwrosewell]

Type of change

• Updated RTD submodule

Description of change

This pull request optimises the ORTB2 enrichment speed for the 51Degrees RTD submodule by eliminating a redundant API call. The changes allow for some device details to be sent directly in the first request, instead of making a second call to the 51Degrees API HTTP endpoint.

• Refactored the get51DegreesJSURL function to include device details such as screen height, width, HEV, and pixel ratio directly in the JS request query string.
• Introduced a new function to retrieve high entropy values from navigator.userAgentData, if supported.
• Updated relevant tests to ensure the new functionality works as intended and to validate the inclusion of device details in the API request.
