Adds requirement on adding maps to the config in MAPS_AND_AWAY_MISSIO…

…NS.md (tgstation#74001)

## About The Pull Request

There's been a surplus of ruin mappers lately, but a lot of them are
unaware that they must be adding their file path to the config so server
operators may toggle them on/off. I had to go through at least four
separate PRs reminding people that this has to be done.

Let's add it to a centralized place regarding maps/mapping such that
it's easier for maintainers to be aware that this requirement exists, as
well as players who are scrounging the github attempting to figure out
what they should do.

 Map files for away missions are located in the `_maps/RandomZLevels` directory. Each away mission includes it's own code definitions located in `/code/modules/awaymissions/mission_code`. These files must be included and compiled with the server beforehand otherwise the server will crash upon trying to load away missions that lack their code.
 
-To enable an away mission open `config/awaymissionconfig.txt` and uncomment one of the .dmm lines by removing the #. If more than one away mission is uncommented then the away mission loader will randomly select one of the enabled ones to load. We also support functionality for config-only away missions, which can be set up using the `config/away_missions` folder.

+## CONFIGURATION
+
+A majority of maps (outlined below) must be placed in their corresponding configuration file to allow server operators to enable/disable the map for any reason they desire. Follow the chart to see where you should add your new map.
+
+| Type of Map | Associated File with Link |
+| ----------- | ----------- |
+| Station Maps | [`config/maps.txt`](https://github.com/tgstation/tgstation/blob/master/config/maps.txt) |
+| Space Ruins | [`config/spaceruinblacklist.txt`](https://github.com/tgstation/tgstation/blob/master/config/spaceruinblacklist.txt) |
+| Lavaland Ruins | [`config/lavaruinblacklist.txt`](https://github.com/tgstation/tgstation/blob/master/config/lavaruinblacklist.txt) |
+| Icemoon Ruins | [`config/iceruinblacklist.txt`](https://github.com/tgstation/tgstation/blob/master/config/iceruinblacklist.txt) |
+| Escape Shuttles |  [`config/unbuyableshuttles.txt`](https://github.com/tgstation/tgstation/blob/master/config/unbuyableshuttles.txt) |
+| Away Missions | [`config/awaymissionconfig.txt`](https://github.com/tgstation/tgstation/blob/master/config/awaymissionconfig.txt) |
+
+Each .txt file will have instructions on how to appropriately add your map to the file. If you're unsure about certain values, ask for help during the PR process (or beforehand).
