Web scraping basics courses: Correct a screenshot, remove notes

[honzajavorek]

All JS examples in sources/academy/webscraping/scraping_basics_python/02_devtools_locating_elements.md have semicolons at the end of the line, except of one. It's an inconsistency and the reader might wonder why suddenly the semicolon isn't there. Currently there is a note which mitigates the problem:

:::note About the missing semicolon

In the screenshot, there is a missing semicolon `;` at the end of the line. In JavaScript, semicolons are optional, so it doesn't make a difference here.

:::

Better solution would be to create a new screenshot with the semicolon in place, so that there's nothing to think about, and then the note can be removed. The same is valid for a similar lesson in the JavaScript course of web scraping basics.
