What this PR does

Adds a new section to the performance documentation (airflow-core/docs/howto/performance.rst) explaining how enabling HTTP/2 at the reverse-proxy layer (e.g. Nginx) removes the browser's six-connection-per-origin limit for HTTP/1.1, which can cause request queuing on busy UI views like the Grid page.

The new section covers:

  • Why HTTP/2 helps (multiplexing eliminates the connection bottleneck)
  • Benefits (lower latency, header compression)
  • How to enable it (Nginx example)
  • Cross-reference to the existing run-behind-proxy docs

Closes #62032
