`create-page-form` is currently only referenced in CSS files.
I've tried researching this with `git log -S 'create-page-form'` and here are the results:
* 80701d45bb - first mention. Introduced `create-page-form` as a Less function/inclusion or something
* 8e0a69f86a - added another usage of it in Less
* 4465c58f4b - seemingly added usage of it as of an actual ID to `gogs.css` (later renamed to `index.css`), still no use in templates
* 045f14fbd0 - unrelated mention in minified bundle
* 3d3faa2624 - ditto + did one property change to it like if it actually changed anything
* d9c67a8c90 - removed built bundle
* 202803fc69 - turned the strange Less thing into a proper pack of `#create-page-form` like if it was used, for some reason, duplicated the new code twice
* ee9e83b230 - removed some of the unused selectors by retiring the `.captcha-field` class, likely not knowing that nothing under `#create-page-form` is used
