Xenomorph Monarch Fixes/Rebalance (#7418)

<!-- Write **BELOW** The Headers and **ABOVE** The comments else it may
not be viewable. -->
<!-- You can view Contributing.MD for a detailed description of the pull
request process. -->

## About The Pull Request

Applies a nerf to Monarch's charge, no longer instantaneous.
Lowers Monarch's burn/energy resist, burn should work better against it
since Xenomorphs are weak to fire.
Axes **any** and all mentions of natural spawn positions, this should
never spawn naturally. It is a boss mob.

<!-- Describe The Pull Request. Please be sure every change is
documented or this can delay review and even discourage maintainers from
merging your PR! -->

## Why It's Good For The Game

This has been an issue for a while, but the natural spawn points for the
Monarch were the last straw. Oopsies.

<!-- Argue for the merits of your changes and how they benefit the game,
especially if they are controversial and/or far reaching. If you can't
actually explain WHY what you are doing will improve the game, then it
probably isn't good for the game in the first place. -->

## Changelog

<!-- If your PR modifies aspects of the game that can be concretely
observed by players or admins you should add a changelog. If your change
does NOT meet this description, remove this section. Please note that
maintainers freely reserve the right to remove and add tags should they
deem it appropriate. You can attempt to finagle the system all you want,
but it's best to shoot for clear communication right off the bat. -->

🆑
balance: lowers Monarch's burn resist, makes charge not instant.
fix: Removes any reference to the Monarch spawning naturally, probable
or not.
/🆑

<!-- Both 🆑's are required for the changelog to work! You can put
your name to the right of the first 🆑 if you want to overwrite your
GitHub username as author ingame. -->
<!-- You can use multiple of the same prefix (they're only used for the
icon ingame) and delete the unneeded ones. Despite some of the tags,
changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->
