What does this PR do? What is the motivation?

Documents a new Synthetic Monitoring capability: use-site variable filters. When you reference a variable in a test, you can now pipe its resolved value through a filter to transform it before it is injected into the request — for example {{ TOKEN | urlEncode }}.

Four filters are supported: urlEncode, urlDecode, base64Encode, and base64Decode. They work for both local and global variables and across all test types, which is why the docs live in the shared synthetics-variables shortcode (included by the HTTP, multistep, browser, mobile, gRPC, SSL, TCP, UDP, WebSocket, DNS, and ICMP test pages).

Merge readiness

  • Ready for merge

Add an 'Apply filters to variable values' section to the shared
synthetics-variables shortcode covering urlEncode, urlDecode,
base64Encode, and base64Decode.
