fix: move writeLogsToFile doc comment to correct position

The buildRegistryAuths function was inserted between the writeLogsToFile
doc comment and the writeLogsToFile function body, causing Go to treat
the writeLogsToFile comment as part of buildRegistryAuths godoc.

Move the writeLogsToFile comment to sit directly above its function,
and keep only the buildRegistryAuths comment above buildRegistryAuths.
