Update import "example" doc text

[drbyte]

A couple words were missing from this paragraph.

Dan, I also wondered about the last line of the doc, which says this:

The current record (if it exists yet) is accessible in $this->record, and the [options](#using-import-options) using $this->options.

I found myself having to "think" about what the word "options" in [options] meant. It took a moment, but then it made sense that it was the "import action form options".
How do you feel about changing the [options] link to [import form options]?
I'm fine with whatever you decide ... just wanted to point it out.

Thanks for all the work that went into this import feature! And its documentation.

Yeah import form options sounds great, thanks!
