[issue32901] Update Windows 3.7/8 builds to tcl/tk 8.6.8

New submission from Terry J. Reedy : This should be done ASAP for most testing. MacOS 64bit 3.7.0b1 links to 8.6.7. Whether that should be upgraded to 8.6.8 is up to Ned. I raised question on #15663. -- messages: 312512 nosy: serhiy.storchaka, terry.reedy,
