request R2026a prerelease

[scivision]

I'm using new R2026a functions "namespaceFunctions" and "innerNamespaces" with publish() to document the matlab-stdlib project that has over 125 functions. However, it seems the R2026a prerelease is not yet enabled by matlab-actions/setup-matlab@v2 with release: "latest-including-prerelease"

Example failing workflow https://github.com/geospace-code/matlab-stdlib/actions/runs/19549746736/job/55977849663

Setting up MATLAB
  /usr/bin/chmod +x /home/runner/work/_temp/mpm
  Installing with the following parameters:
  --destination=/opt/hostedtoolcache/MATLAB/2025.2.999/x64
  --release=R2025b
  --products=MATLAB

but I expected --release=R2026a

There is still some work to do before we can open up the R2026a prerelease. I will post back on this issue when it is available.
