When a response is compressed, Envoy strips strong ETags by default (weak ETags are preserved). Users discovering this at runtime was the source of some confusion; add a short section that documents the default and links to the upstream Envoy compressor filter docs for the tunable options (disable_on_etag_header, weaken_etag_on_compress).

What this PR does / why we need it:
Adds a short section to the Response Compression task noting that Envoy strips strong
ETagheaders by default when compression is applied, and links to the upstream Envoy compressor filter docs for the tunable options (disable_on_etag_header,weaken_etag_on_compress).Users in #8805 found this behavior surprising because it was not mentioned on the task page.
Which issue(s) this PR fixes:
Fixes #8805
