It is known that Gimp 2.10.x renders text, especially small text on the light side. Some difference in anti-aliasing from previous versions. There was a bug report about this but not able to find it at the moment.
One way out is duplicate the text layer so that they reinforce each other.

Then merge them if editing text is no longer required.
