[clangd] Fix code action kind for readability-identifier-naming fixes (#162808)

#78454 converted
readability-identifier-naming fixes to use rename mechanism to rename
the symbol project-wide. However, it set the code action kind to
"refactor" instead of "quickfix", which caused the fixes to be filtered
out when editors (like VS Code) request quick fixes for diagnostics. On
VS Code, for example, users would see "No quick fixes available" despite
the diagnostic indicating "(fix available)".

Fix that by changing the code action kind back to "quickfix".
