The most common limit for the maximum number of allowed documentation
warnings is zero. Use a global value for 'warninglimit', adopted by
all Qt module documentation projects that include the configuration
from qtbase/doc/global.
This allows for a temporary increase of the limit across all modules as
needed - for example, when updating the QDoc binary that the CI
provisions to a version that introduces new types of documentation
warnings.
Increase this base limit temporarily to 10 to help re-enable
documentation testing in CI as it's currently disabled.
