### Steps to update the qt6 ports
## 1. Change QT_VERSION below to the new version
## 2. Set QT_UPDATE_VERSION to 1
## 3. Add any new Qt modules to QT_PORTS
## 4. Run a build of `qtbase`
## 5. Fix any intermediate failures by adding the module into QT_FROM_GITHUB, QT_FROM_GITHUB_BRANCH, or QT_FROM_QT_GIT as appropriate
## 6. The build should fail with "Done downloading version and emitting hashes." This will have changed out the vcpkg.json versions of the qt ports and rewritten qt_port_data.cmake
## 7. Set QT_UPDATE_VERSION back to 0
