docs: replace deprecated match_config with match in tap filter examples (#43955)

## Summary
- Replace the deprecated `match_config` field with `match` in all 7 YAML
examples in the tap filter documentation
- `match_config` has been deprecated since v3.0 (see
`api/envoy/config/tap/v3/common.proto`)
- Both fields use the same `MatchPredicate` type so the YAML structure
is unchanged

Fixes #20190
Continues the work from #20194.

Risk Level: Low (docs only)
Testing: N/A
Docs Changes: Updated all tap filter examples
Release Notes: N/A
