[Bug]: exception in list-qt for android target

Bug description

Run aqt list-qt <TARGET> android. Where <TARGET> is one of linux, mac, windows.

The command crashes without any useful information provided to the user. Other list-* commands seem to work.

Tested in virtual environment and system-wide pip install which both result in the same behavior.

Expected behavior

A list of Qt versions.

aqt and python version

aqtinstall(aqt) v3.1.18 on Python 3.12.3 [CPython GCC 13.2.0]

Operating System

Linux/Unix

Relevant log output

Looks like the Qt maintainers changed the directory structure, again.

Incomplete listing of directories at https://download.qt.io/online/qtsdkrepository/linux_x64/android/:

qt6_600_x86_64/
qt6_600_x86/
qt6_600_armv7/
qt6_600_arm64_v8a
qt6_600/
qt6_7_3/
qt6_7_2/
qt6_7_1/
qt6_7_0/
qt5_51212/
qt5_51211/
qt5_51210/

Currently, the following code splits up the folder name on _, and the string of digits following qt5 or qt6 is interpreted as the version of Qt. So, 51212 gets split up into 5.12.12 and 600 gets split up into 6.0.0. However, qt6_7_3 gets mangled, because aqt thinks that 7 is the whole version string, when it actually refers to version 6.7.3.

https://github.com/miurahr/aqtinstall/blob/73fc45e12a0a8e2e417fee12b6813b6a82dc9324/aqt/metadata.py#L779-L786

Also see get_semantic_version_string here: https://github.com/miurahr/aqtinstall/blob/73fc45e12a0a8e2e417fee12b6813b6a82dc9324/aqt/metadata.py#L172-L197

Please also note that this means it is currently impossible to install Qt 6.7.* for Android without using the all_os directory, because the installer won't be able to find these folders either.
