docs(cctv): Ontario 511 docs match the key requirement and the developer agreement

Review fixes for #1228: CURRENT-STATE.md and the constants comment no
longer call Ontario 511 keyless. DATA_SOURCES.md notes Ontario 511's
Developer's Access Agreement (511on.ca/developers/resources): the data
stays under the Open Government Licence - Ontario, key requests are
reviewed case by case, attribution by link is encouraged and the logo
rules don't apply because the app shows none, and the "as is" disclaimer
should be passed on, which the credit now does.
