[wasm] Fix linux/arm64 build (#68492)

Don't checkout particular emscripten version and instead use main.

It is not needed and fixes linux/arm64 build, where precompiled version
is available in emscripten 3.1.7 and later versions.
The `emsdk install|activate <version>` doesn't work correctly for 3.1.7
tag and does with uptodate main.

It will still install and activate the emscripten version we want, like 3.1.7 currently.
