[FEATURE] Improve bot behavior

[agustinesco]

🚀 Features

• General design notes: https://www.notion.so/lambdaclass/Bots-9468222e8eba48c187d88aefeb22827e
• Bots need to use the playable characters (Active boolean in Configurator database (/characters endpoint).
• They need to either have tailored AI for the different characters and/or understanding of ButtonTypes, or anything else you can come up with so they work with all heroes. New columns can be added to the character/skills JSON to aid this feature as well, if needed We should probably indicate internally in each skill whether it's short/med/long range so the bots have better understanding of when to use them
• Players that leave should continue to play as bots -> @agustinesco will put issue here.
• Prevents bots from stacking on top of each other (they should respect some distance to any target)
• [FEATURE] - Make bots movement less clumsy  #1003
• They should reduce their engaging chance when under 25% health and try to seek cover (i.e. find a place without many units)
• Bots need to be made aware of the shrinking circle (battle royale)
• Check if there are other issues that could break their behavior (sometimes they get stuck against walls) that could be a result of the implementation of various features since they were first added
