caddy: update to 2.6.4

v2.6.4

This release contains a hotfix for a regression in v2.6.3 related to proxying
chunked requests. We recommend that all users who do so upgrade to v2.6.4.

v2.6.3

This release brings a number of bug fixes and minor features. We recommend that
all users check the release notes/commits, then test and upgrade.

Notable changes:

- New trusted_proxies global option (within servers) can be used to specify
  trusted proxy IP ranges globally. This is important if relying on headers for
  client IP addresses.
- Unix sockets on Windows now supported as proxy upstreams.
- Proxied WebSocket connections are now logged with correct status code and
  "size" (bytes read + bytes written).
- The quic-go package has received significant optimizations, so HTTP/3 should
  be more efficient now.
