Minor typo on warnings

[MicaelJarniac]

pandas/pandas/_libs/parsers.pyx

Lines 1993 to 1996 in 25110a9

	warning_message = " ".join([
	f"Columns ({warning_names}) have mixed types."
	f"Specify dtype option on import or set low_memory=False."
	])

"Columns ({warning_names}) have mixed types.Specify dtype option on import or set low_memory=False."
Note the lack of a space after the period on types.Specify. That's because there's no comma separating the strings inside the list, so they get appended while still inside the list, and get passed as a single string to " ".join(...), thus it has nothing to join.
Simply adding the missing comma should fix it.

Just wanted to know if this issue still persists ? Because I think it is already fixed in #39159 .
Am I supposed to find such warning messages in the source code and fix them?

[MarcoGorelli]

#39159 wasn't merged, so it looks like this is still open
