Building Web export templates for 3.5.3 on Windows fails parsing emcc version

[AnnA-Ayms]

Godot version

3.5.3

System information

Windows 10

Issue description

Can't build a web template (at least under Windows 10) with the current 3.5.3 build as is (necessary if Compiling project with PCK encryption key).
relates to changes after #81340

Commenting out line 189 "cc_semver = tuple(get_compiler_version(env))" of \godot-3.5\platform\javascript "detect.py"
and I was able to compile the template since neither
"if env["use_thinlto"] or env["use_lto"]:" nor "if env["gdnative_enabled"]:"
apply to my use but investigation by someone more competent on these matters than me would be good.

results before the comment out
Z:\godot-3.5>scons platform=javascript tools=no target=release

Same error for me.
Win10, Visual Studio 2022, emsdk 3.1.46

Same issue here, Vscode 2022, emsdk 3.1.14
Seems like get_compiler_version(env) return a none type not the emsdk version tuple
I change the code to cc_semver = (3,1,14) and it fixed
