Make --timeout option consistent across all commands (including javascript)

[beetleb]

Currently the javascript command doesn't support a timeout option.

(Wider context: I'm trying to use Readability as you described here).

Huh, right now the sub-commands shot and multi and accessibility have the --timeout option but javascript and html and pdf do not.

It's used like this:

shot-scraper/shot_scraper/cli.py

Lines 432 to 434 in 0268b0c

	context = browser_obj.new_context(**context_args)
	if timeout:
	context.set_default_timeout(timeout)

So it needs to be passed like this:

shot-scraper/shot_scraper/cli.py

Lines 520 to 532 in 0268b0c

	with sync_playwright() as p:
	context, browser_obj = _browser_context(
	p,
	auth,
	scale_factor=scale_factor,
	browser=browser,
	browser_args=browser_args,
	user_agent=user_agent,
	timeout=timeout,
	reduced_motion=reduced_motion,
	auth_username=auth_username,
	auth_password=auth_password,
	)
