OTP 28 support

[mayel]

Compiling on OTP 28 fails because regex are no longer allowed in module attributes:

== Compilation error in file lib/ex_json_schema/validator/format.ex ==
** (ArgumentError) cannot inject attribute @formats into function/macro because cannot escape #Reference<0.3862611929.2693398537.188290>. The supported values are: lists, tuples, maps, atoms, numbers, bitstrings, PIDs and remote functions in the format &Mod.fun/arity

Thank you for reporting that. I will include that version in the build matrix and take care of the fix today.

OTP 28 isn't supported on GH Actions yet, adding it to the build matrix will have to wait a bit.

Ok, I cherry-picked your commit and released the fixed version as 0.11.1. Thank you for pointing this out and helping with a fix 🙇
