Hackney ignores cacertile option in the request

[tomekowal]

Hi!

I've made a branch with reproduction.
https://github.com/tomekowal/hackney/tree/fix/cacertfile-ignored-with-conn (first commit is just the failing test)

I believe the problem might be somewhere in:

hackney/src/hackney_conn.erl

Line 2273 in a33e878

hackney_ssl ->

I think it should use:

hackney/src/hackney_ssl.erl

Line 55 in a33e878

merge_ssl_opts(Host, OverrideOpts, Options) ->

because that one removes cacerts when cacertfile is present.

I will open a PR with it, but it is generated by Claude, so feel free to discard it.
