Adding more formatting edge cases to the documentation

To avoid possible confusions among users, which are not do familiar with Markdown, I would suggest adding more “finer points” and “edge cases” about Markdown formatting to the Obsidian help (i.e., How to format your notes).

Some points I am missing in the documentation are listed below.

Adding block content to list items

- First paragraph.

    Second paragraph. With a code block, which must be indented by eight spaces:

        { code }

which renders like this:

  • First paragraph.

    Second paragraph. With a code block, which must be indented by eight spaces:

      { code }
    

Including backticks in inline code

Here is a literal backtick `` ` ``.

which renders as:

Here is a literal backtick `.

Including backticks in fenced code blocks

````
```
code including backticks
```
````

which renders like this:

```
