Add support for role mentions on the bot's autogenerated managed roleid.

[Ifiht]

Summary

This is to address the discrepancy when a user types the bot's exact name, and discord translates it to a role mention due to the autogenerated managed role that's created when adding a bot with permissions > 0 to a server. Below is an example of the new behavior from an irb session:

3.1.4 :003 > bot.run :async
[INFO : websocket @ 2024-06-05 09:54:55.116] Discord using gateway protocol version: 9, requested: 9
 => nil
3.1.4 :004 > bot.mention(allow_role_mention: true) do |event|
3.1.4 :005 >     puts "THIS FIRES FOR USER & ROLE MENTIONS: #{event.content}"
3.1.4 :006 > end
 => #<Discordrb::Events::MentionEventHandler:0x000055742aa345c8 @attributes={:allow_role_mention=>true}, @block=#<Proc:0x000055742aa34a00 (irb):4>>
3.1.4 :007 > bot.mention() do |event|
3.1.4 :008 >     puts "THIS ONLY FIRES FOR USER MENTIONS: #{event.content}"
3.1.4 :009 > end
 => #<Discordrb::Events::MentionEventHandler:0x000055742ab280d8 @attributes={}, @block=#<Proc:0x000055742ab282b8 (irb):7>>
3.1.4 :010 >
3.1.4 :011 > 
THIS FIRES FOR USER & ROLE MENTIONS: <@1211423563475849236> user mention test
THIS ONLY FIRES FOR USER MENTIONS: <@1211423563475849236> user mention test
THIS FIRES FOR USER & ROLE MENTIONS: <@&1211432785353637999> role mention test

in the above test, I sent two messages to the bot, one with a role mention and the other with a user mention. The blocks passed demonstrate that only when :allow_role_mention == true will the event be raised upon role mentions.

All tests were run with bundle exec rspec spec and passed:

Changed

• discordrb/events/message.rb
• discordrb/bot.rb
• discordrb/container.rb

additionally the gemspec was updated to include the role_mentions: flag, to avoid a no method error but otherwise function is exactly the same.

Fixed

You could say the bot.mention function has been "fixed"? Depends how you view this feature & support for Discord's managed roles.
