Release 0.26.5

What's New

This build has no functional changes, but does have changes to the build workflow,
because github is deprecating certain action runners. See
https://github.blog/changelog/2022-08-09-github-actions-the-ubuntu-18-04-actions-runner-image-is-being-deprecated-and-will-be-removed-by-12-1-22/
and

for details

• MacOS builds are now done on the macos-11 github builder
• Linux builds are now done on the ubuntu-20.04 builder

This changes the oldest supported operating system versions for ziti-controller and ziti-router to those
listed above, due to dependencies on system shared libraries that may not be available on older operating
system versions.
