reduce the amount of spelling issues / WORDLIST

[m7pr]

The follow-up after https://github.com/insightsengineering/coredev-tasks/issues/235

The current spelling-check output is below. omics is a part of multi-omics. pre-selected is treated as spelling mistake either if it's written pre-selected or preselected. themer and theming are a part of subject-language about themes. tabsetted does not seem to be an English word, even though TabSet class became of common word around developers.
