Default: `==3.1.*`

Default: `==0.20.*`

`Qt5_DIR` is also set appropriately for CMake if you are using Qt 5.

* Updated `aqtinstall` to version 3.1.* by default.

* Use the `--autodesktop` flag to automatically install the desktop version of Qt, parallel to any WASM or mobile

versions of Qt 6.2 and above.

* If your action installed Qt 6.2+ for Android or WASM using `install-qt-action@v3`, then your action would have

needed to install the desktop version of Qt alongside the WASM/mobile version of Qt, otherwise it would not have

worked properly. As long as you are using `aqtinstall v3` or higher, the new version of `install-qt-action` will do

that automatically, so you can remove the second step where you add the parallel desktop version of Qt.

If you don't, your workflow will install desktop Qt twice.

* Added the `QT_ROOT_DIR` environment variable that points to the root of the Qt installation.

This variable points to the same directory as the old `Qt5_DIR` and `Qt6_DIR` variables.

* Changed `Qt5_DIR` environment variable, so that it points to `${QT_ROOT_DIR}/lib/cmake`, as required by CMake.

If your action uses this variable for any other purpose, you should update it to use `QT_ROOT_DIR` instead.

* Removed the `Qt5_Dir` and `Qt6_DIR` environment variables, because they are not used by CMake.

If your action uses these variables, you should update them to use `QT_ROOT_DIR` instead.

* Updated `aqtinstall` to version 2.1.* by default.

See [changelog entry](https://github.com/miurahr/aqtinstall/blob/master/docs/CHANGELOG.rst#v210-14-apr-2022) for details.

* `aqtinstall` v 2.1.0 now checks that the SHA256 checksums reported at https://download.qt.io matches the 7z archives

that it downloads [aqtinstall#493](https://github.com/miurahr/aqtinstall/pull/493).

This change was necessary because the old checksum algorithm, SHA1, is no longer safe to use for this purpose.

Unfortunately, SHA256 checksums are often not available for up to 24 hours after new 7z archives are made available at

https://download.qt.io, and workflows that use `aqtinstall` v 2.1.0 will fail to install Qt properly during that window.

See [aqtinstall#578](https://github.com/miurahr/aqtinstall/issues/578) for further discussion.
