Remove [sic] display for misspelled words

[kmcmullen]

We want to remove the "[sic]" and yellow highlighting that appears after a misspelled word across the site (particularly in the correspondence). We now have the squiggly underlining that indicates a misspelling, so the "sic" is no longer necessary and is slightly confusing. See, for example, the second paragraph here: https://cdrhdev1.unl.edu/chesnutt/item/ccda.corr00152 (the word "artcile")

I was able to fix this just by commenting out the relevant code in the tei_to_html overrides stylesheet on the dev branch. We'll just need to move that over to the main branch before we next publish a batch (which is maybe standard practice anyway?). I'll close this.
