Convar missing from docs

[SkylarPlayz348]

I noticed that some people are getting the no such export as whatever it is for customization. I then looked at the docs on the website then I noticed that in one of the branches there was a convar called fivem-appearance:customization but on website it isn't in the installation but there is a mention of it when it talks about it needing a specific value. I have made a pr here https://github.com/fivepunch/docs/pull/4 to fix said issue. For those having the error with customization add setr fivem-appearance:customization 1 to your server.cfg where you setup the rest of the script
