Update for latest TableauScraping and protect against failures due to breaking changes in that library

[brentajones]

I have a Github Actions scraper using this that started erroring out earlier today. Digging into the code a little, I found this update to TableauScraping, which seems like it renamed dashboards to workbooks? I don't know enough about the code to know for sure.

My error log says:

AttributeError: 'TableauScraper' object has no attribute 'getDashboard'

Thanks for reporting this - yes it looks like that TableauScraping library is still pretty unstable (it's pre-1.0). I'm going to upgrade this script, then pin a version and switch to using Dependabot to apply future upgrades.

I've enabled Dependabot, so hopefully it will create a pull request bumping TableauScraper shortly... which should fail, because of this breaking change.

... that worked, here's the Dependabot PR: #5

... and the tests for that failed with:

>       assert result.exit_code == 0
E       assert 1 == 0
E        +  where 1 = <Result AttributeError("'TableauScraper' object has no attribute 'getDashboard'",)>.exit_code

OK, this should be fixed in the new release: https://github.com/simonw/tableau-to-sqlite/releases/tag/0.2.1
