Rename record type to cache_record type to fix compilation on Erlang 29.0

[TBK145]

Erlang 29 (release candidate 1) doesn't allow built-in types (like record) to be redefined.
This leads to the following compilation error:

==> cachex
Compiling 56 files (.ex)

== Compilation error in file lib/cachex/spec/validator.ex ==
** (Kernel.TypespecError) lib/cachex/spec/validator.ex:14: type record/0 is a built-in type and it cannot be redefined
    (elixir 1.19.5) lib/kernel/typespec.ex:992: Kernel.Typespec.compile_error/2
    (stdlib 8.0) lists.erl:2465: :lists.foldl/3
    (elixir 1.19.5) lib/kernel/typespec.ex:230: Kernel.Typespec.translate_typespecs_for_module/2

I renamed the type record to cache_record to fix this.

I'm thinking now that I misinterpreted the issue, and it was already not allowed to redefine built-in types, but Erlang 29 ships with record as a new type.

Hi @TBK145, thanks for reporting!

I don't have spare time right now, but I can definitely look into this and make sure we fully understand what changed. Fortunately I'm planning a major version anyway, so the breaking change here won't matter as much.

Hey, erlang/OTP 29 is now available, so it would be great to get this merged when you have time.
