This PR refreshes meta descriptions and titles for content in the /hcl_templates /functions folder to improve SEO.

Instead of the "Learn how to..." summaries in these, would we want to note the other types of information users will find on the page? For example I looked at the first few, and it seems like these pages contain "examples" (which I bet lots of people will google for) and relationships to other functions?

You are correct that people also search for "examples of . . .". I went for the phrase "how to . . . " because that is usually a stronger initial search phrase. Trying to do too much in meta descriptions usually dilutes the discoverability. It's better to focus on either "examples of . . . " or "how to . . . "

Either way, the main keywords we are optimizing for is the function names, which means that searchers would already have to know the name of the function they are Googling. It's kind of a catch-22, though, because if they know the function name, they will definitely land on these pages regardless of the secondary "how to" or "examples of" phrase. But they would have to know the name of the function.

My only worry here is helping users land on the right content type. If someone is looking for a how-to and they land on these pages they might be sad, and if we add how-to pages in the future, including "how to" in these descriptions might make it harder for users to find the right thing. Functionally it probably doesn't matter a ton now though!
