fix(nesdoctor): the closing prose still said "launch times"

Missed when the histogram was corrected: the tool spent a paragraph asking
people to send the JSON and described it as holding "installed titles with
sizes and launch times", which is the same claim the histogram itself no
longer makes. Steam stores when a title was last played, not each time it was
launched.

Found by running the installer end to end after the release — the shipped
0.3.0 binary prints it. Fixed here for the next one; it is prose in the
closing paragraph, not a number anybody acted on.

Same wording in the --json flag's doc comment, in the submit URL's comment,
and in the consent prompt that asks to read the library at all. That last one
matters most of the four: it is what somebody reads before saying yes.
