Rollup merge of #33322 - justsostephen:master, r=steveklabnik

doc/book/getting-started.md: Spelling correction and revised wording.

The word 'Internet' was spelt with both an uppercase and a lowercase 'I'. The correct spelling seems to be a matter of some debate these days, however the first occurrence in the file has an uppercase 'I', so I've changed the second occurrence to suit for consistency.

Under the section titled 'Converting to Cargo', there's mention of creating a new executable. This, however, is not part of the process described. I've revised the wording to reflect as much.

Small changes, but I hope they are of benefit! :-)
