Bump version to 5.4.2

Code that relies on `resend_count` was added in 7ea4a03 and 247a1eb, but never worked.
This was fixed in #11607 which caused the problem to surface.
Hence undo the first commit entirely and change the logic of the second.

 5. It uses protocols and formats which include the required compatibility.
 
+### Important note about automated GitHub checks
+
+When you submit a pull request, GitHub automatically runs checks on the Minetest Engine combined with your changes. One of these checks is called 'cpp lint / clang format', which checks code formatting. Because formatting for readability requires human judgement this check often fails and often makes unsuitable formatting requests which make code readability worse.
+
+If this check fails, look at the details to check for any clear mistakes and correct those. However, you should not apply everything ClangFormat requests. Ignore requests that make code readability worse and any other clearly unsuitable requests. Discuss in the pull request with a core developer about how to progress.
+
 ## Issues
 
 If you experience an issue, we would like to know the details - especially when a stable release is on the way.
