Update Fedora section of the README.md file (#4792)

After discussion from the following PR (
#4362 ) I have finally
found time to make a PR to update the Fedora section of the README.md
file. I actually use those instructions myself from few different Fedora
and Amazon Linux 2023 machines.

Here is an example of installing lazygit from the Copr:

```
» sudo dnf install lazygit

Package                                                              Arch        Version                                                              Repository                                                  Size

Transaction Summary:
 Installing:         1 package

Total size of inbound packages is 6 MiB. Need to download 6 MiB.
After this operation, 22 MiB extra will be used (install 22 MiB, remove 0 B).
