**What kind of change does this PR introduce?**
Typo fix in the documentation
**Did you add tests for your changes?**
No
**If relevant, did you update the documentation?**
N/A
**Summary**
I spotted the `Visible` parameter had an uppercase `V` in the [Remarks
section of the Page.waitForSelector API
documentation](https://pptr.dev/api/puppeteer.page.waitforselector#remarks).
Updated this to the lowercase `v` in the relevant places (source,
documentation, versioned version of the doc page).
While doing this, I also spotted there was an extra space in `are :` in
the sentence above – so changed that as well.
**Does this PR introduce a breaking change?**
No
**Other information**
I’ve confirmed the parameter is spelled correctly on
https://pptr.dev/api/puppeteer.waitforselectoroptions. I’m not sure why
the documentation for those properties is in two places with slightly
different wording – but to me it felt useful to see this directly on the
method’s API docs.
