[Feature]: Make text fields behind checkboxes clickable

[JohannaOtt]

Is your feature request related to a problem? Please describe.
When exporting geopackage data, the options "Overwrite target file if it exists" and "Also create tables for types that have no instances" can only be enabled when clicking on the checkbox in front of the text.

Other options such as "Convert all geometries to the given target CRS" on the dialogue page before can also be activated by clicking on the text line.

Describe the solution you'd like
I would like to be able to activate all checkboxes by clicking on the text as well.
