docs/packaging: Replace install commands with new macros

@@ -97,6 +97,8 @@ For this example, we need to fix the following:
 - Remove `builddeps`. This package has no build dependencies beyond the ones already available for every package (the `system.devel` packages).
 - The `setup` step is not required, remove it.
 - In the `install` key, we can't use the `%make_install` macro for this package. The files are installed in their correct locations individually.
+    - The `%install_file` macro installs a file to a target location with the correct permissions.
+    - The `%install_bin` macro installs the binary to the binary directory with the correct permissions.
 
 After updating the file, it will now look like:

 ## Installing extra files
 
-We recommend using patches where possible first, as they ensure correct maintenance and will be updated across package versions. If you must install extra files into the directory, please use the `install` command, ensuring you set the correct permissions. Again, files are accessible from the `./files` directory, relative to `package.yml`.

 This is an example of installing a custom profile file, seen in the `bash` package:
 
 ```bash
-install -m 0644 $pkgfiles/profile $installdir/etc/profile
+%install_file $pkgfiles/profile $installdir/etc/profile
 ```
