Title: [clock] regression in tzdata (TZ generation in tclZIC seems not support new iana database format, e. g. %z instead of offset TZ-name)

Description:

[9275edd424971958] introduced a regression: several TZs got wrong time zone names (%z instead of TZ-offset name).

The reason looks like "tools/tclZIC.tcl" didn't support the change on the format for IANA time zone database 2024b.

I'm preparing a branch bug-fix-tz-w-offs fixing tools/tclZIC.tcl and few other small bugs around it found by tests and attempt to fix github/tclclockmod#24. The branch is initiated as 8.5-based branch to avoid the regression in 8.5 by regeneration of tzdata with tools/tclZIC there.

This was also released with 8.6.15 and 9.0, so I guess it must be rereleased soon or a quick patch must be provided for maintainers.

Fixed in all branches now, thus close it.

For the patch of 8.6.15 see [6a166839ed62c9c1], 9.0 - [ab6663673f92f81f].
