Remove cached certificate about lua-resty-auto-ssl HOT 1 OPEN

Initially it looks like the issue started from the lua_shared_dict being too small, as per the logs:

2024/03/02 16:13:23 [error] 2006421#2006421: 154079 [lua] ssl_certificate.lua:33: convert_to_der_and_cache(): auto-ssl: 'lua_shared_dict auto_ssl' might be too small - consider increasing its configured size (old entries were removed while adding private key for example.com), context: ssl_certificate_by_lua, client: 213.230.127.224, server: 0.0.0.0:443

I've subsequently increased the size of the shared dict, but now any domains that requested certs in this period are now getting the invalid cert response described above. I thought perhaps purging the lua_shared_dict might be the solution, although I've tried ngx.shared.auto_ssl:flush_all() and this isn't having an effect.

Perhaps more related to Nginx/openresty?
