Build images for emqx/otp 28.4.1-6 (tag OTP-28.4.1-6) alongside 28.5.0.7-1. This brings #167 back as a second 28 line instead of a replacement.

EMQX v6 (6.1, 6.2, 6.3) stays on OTP 28.4. Since OTP 28.5.0.1 (RFC 9525), hostname verification no longer falls back to the subject CN when a server certificate has no subjectAltName. On v6 that would be a breaking change for TLS client connections. 28.5.0.7-1 remains for v7.

28.4.1-6 adds the ssl memory changes from emqx/otp#113 and #114 to 28.4.1-5: shared socket options in atomics instead of one ETS table per connection, and dropping AEAD handles on idle TLS 1.3 connections.

After merge, push tag 6.1-11 to build and publish the images.
