[HelpHub] Various small issues in the Glossary doc

Issue Description

• In the introduction to the Glossary it says "If you are a contributor please don’t add definitions for generic terms (API, PHP, JavaScript, etc…).". But there are glossary entries for all these terms.
• https://wordpress.org/support/article/glossary/#bookmarklet - 'their' would be more gender-inclusive than 'his/her'.
• https://wordpress.org/support/article/glossary/#cvs - typo, "‘used to be used coordinate WordPress development." should instead be "‘used to be used to coordinate WordPress development.’.
• https://wordpress.org/support/article/glossary/#blog - this definition is maybe a bit outdated as it is more common for corporations to use blogs now
• https://wordpress.org/support/article/glossary/#moblogging - I'm not sure how many people understand this pronunciation transcription system (I don't).
• https://wordpress.org/support/article/glossary/#quicktag - I think the 'Back to the top' link shouldn't be here but at the very bottom of the page
• https://wordpress.org/support/article/glossary/#rdf would be nice if ‘RSS’ hyperlinked to the glossary entry for RSS
• https://wordpress.org/support/article/glossary/#unicode - “The most widely used collections of these character sets are the iso-8859 with iso-8859-1 and iso-8859-15 (which contains the euro sign and some characters used in Dutch, French, Czech and Slovak)“ -> I’m not sure why those languages specifically are named, it sounds a bit strange. According to the Wikipedia page, there are characters from more languages in iso-8859-15

Why is this a problem?

Suggested Fix

Start at the Glossary page linked in the issue and inspect the entries at #bookmarklet, #cvs, #blog, #moblogging, #quicktag, #rdf, and #unicode, along with the introduction. Review the listed wording, link, placement, pronunciation, and inclusivity concerns; done means the agreed corrections are reflected consistently in the published glossary.
