GH-49426: [Python] Do not build pyarrow-stubs on emscripten builds (#49427)
### Rationale for this change
The emscripten job is currently failing due to pyarrow-stubs building.
### What changes are included in this PR?
- Do not build doc stubs for emscripten build as it tries to install
pyarrow which is unavailable.
- Minor fix for chrome as it was timing out without being able to download
wasm wheel.
- Fix loading tzdata as some tests were failing without it.
### Are these changes tested?
Yes via archery.
### Are there any user-facing changes?
No
