docs: shortcode formatting and typo(s)

[Thoughtscript]

Description

Some small changes to documentation to get familiar with CI/CD, tooling, etc.

Thanks!

Issue

1. Some nitpicks/fairly trivial typos fixed.

2. Per API style/conventions guide #26190 - Shortcode command looks like it should be background highlighted but isn't wrapped by a p tag.

   Screenshot:

   

   Should be:

   

Think the include and shortcode gets used in all of the language translations.

Reviewers: you can see an example of the change on this page /docs/tasks/inject-data-application/define-command-argument-container/

Closes: #48621

Sorry about misunderstanding the change before. To make this easiest to review, please split this PR into two:

• one PR that changes the shortcode only
• one PR that only fixes English content

/hold
pending that split

OK to unhold if the PR is now a single commit that only includes one of the above changes.

@Thoughtscript if you're not sure about how to do that split, we're happy to explain further.
