Issue-1421: Rewrote MysteriousRuinPlugin to a Listener

What has been done in this MR?

• Fixes #1421 (closed)
• Rewrote MysteriousRuinsPlugin to a Kotlin InteractionListener (#230)

What should testers check?

• Players should never be able to access Runic altars if they haven't completed Rune Mysteries
• Players should be able to access the relevant runic altar through the mysterious ruin while wearing the correct tiara or using the correct talisman
• In both cases (tiara / talisman) the player should receive the Varrock easy task completion upon entering the earth runic altar

• I have tested these changes thoroughly.

• I used the relevant Thanos/Zaros tool for any JSON edits where possible, and have attached screenshots of any changes.
