Most packages that used fetchFromGitea fetch their sources from Codeberg, so might as well migrate them.
The following command was used for this treewide:
```fish
for i in (rg 'fetchFromGitea \{\n *domain = "codeberg.org";' --multiline --files-with-matches)
sed -z 's/fetchFromGitea {\n *domain = "codeberg.org";/fetchFromCodeberg {/g' $i > $i.tmp && mv $i.tmp $i
sed -i 's/fetchFromGitea/fetchFromCodeberg/g' $i
end
```
The following paths were manually edited:
* pkgs/by-name/xr/xrsh/package.nix
* pkgs/applications/networking/browsers/librewolf/src.nix
* pkgs/by-name/go/gotosocial/package.nix
* pkgs/by-name/ka/katawa-shoujo-re-engineered/package.nix
