[Bug]: BigQuery table name validation doesn't allow spaces

[zchenyu]

What happened?

BigQuery IO currently rejects table names that contain spaces.

From https://cloud.google.com/bigquery/docs/tables#table_naming : a table name can contain spaces.

Looks like it will require an update to this regex:

beam/sdks/python/apache_beam/io/gcp/bigquery_tools.py

Line 258 in ac20321

r'^((?P<project>.+):)?(?P<dataset>\w+)\.(?P<table>[-\w\$]+)$', table)

Similar to this PR which allowed - in table names: #14125

@BjornPrime This has intersections with I/O, but this could be a good starter bug to get you used to the workflow of testing, making a PR, etc.
