Add more well-known categories #14

Description

@ScriptRaccoon

While CatDat already has a couple of well-known categories, some are currently missing. Here are some suggestions.

Notation Category Links
$grMod_R$ Graded modules  
$CGWH$ compactly generated weak Hausdorff spaces  
$hTop$ Homotopy category of Top  
$Haus$ Hausdorff spaces  
$CompHaus$ Compact Hausdorff spaces  
$TopGrp$ Topological groups  
$Ban_c$ Banach spaces with continuous linear maps  
$TopVect$ Topological vector spaces  
$NormVect$ Normed vector spaces  
$CompMet$ Complete metric spaces MSE
$C^*-Alg$ C*-algebras  
$LawMet$ Lawvere metric spaces  
$Mod(O_X)$ Modules over a sheaf of rings  
$RS$ Ringed spaces  
$Qcoh(X)$ Quasi-coherent sheaves  
$Alg(O_X)$ Algebras over a sheaf of rings  
$\Delta$ Simplex category  

Also:

  1. Add the categories from https://math.stackexchange.com/questions/4481902/locally-presentable-vs-compactly-presentable-categories
  2. Add the categories from https://mathoverflow.net/questions/258269/cocomplete-topoi-that-are-not-grothendieck

IMPORTANT. Adding these categories to the categories table is easy, but not sufficient, since (see CONTRIBUTING.md) one should also try to fill in the properties and non-properties (in case they are not deduced already). So this is actually a quite big task. Maybe one can make one commit (or PR) per category.
