Maya 2026 build request

**Is your feature request related to a problem? Please describe.**
There are only release builds for the latest point release of Maya 2026.2. But for productions started with the original 2026 release these plugins are not binary compatible, so the production is stuck with the older, buggier version of the maya-usd plugin. On the other hand for example Bifrost and Golaem is compiled for Maya 2026 and is usable for both 2026 and 2026.2. It does not make much sense that only the USD plugin update is unusable out of the box.

**Describe the solution you'd like**
I'd like to have builds for the original Maya 2026 release version.

**Describe alternatives you've considered**
Compiling my own build can be done, but compiling USD and all its dependencies is a major PITA. And having compatibility with the ADSK build matrix can be tricky, and the differences further complicates error reporting.

**Additional context**
-

Start by reviewing the existing release-build process for Maya 2026.2 and how the repository represents its supported Maya versions. Done means a release build is available for the original Maya 2026 version and is usable for productions targeting that release.
