doc: interpret-trailers: rewrite new-trailers paragraphs

Two commits ago we moved new-trailers paragraph next to each other.
But there is something curious about two of them:

    By default the new trailer will appear at the end of the trailer
    block. [...]

Then a source block and a paragraph later:

    By default, a `<key>=<value>` or `<key>:<value>` argument given
    using `--trailer` will be appended after the existing trailers only
    if [...]

Why are there two paragraphs that talk about how “By default” a trailer
will be appended?

We can make these paragraphs flow better, and with a more distinct
character each, by dividing the flow like this:

1. Declare that we are about to talk about `--trailer` appending
2. Explain the default behavior
3. Explain how this affects the trailer block
4. Then discuss what each trailer line will look like

Also by default, this new trailer will only be added

A trailer block will be created with only that trailer if a trailer
block does not already exist. Recall that a trailer block needs to be
preceded by a blank line, so a blank line will be inserted before the
new trailer block in that case.
