🕷️ Fix spider: Illinois Commerce Commission

[SimmonsRitchie]

What's this PR do?

Fixes our Illinois Commerce Commission spider (aka. il_commerce), which broke due to URL and HTML changes on the target webpage.

Why are we doing this?

We want working scrapers, of course 🤖 The changes in this PR include targeting a slightly different URL and using new CSS selectors.

Steps to manually test

After installing the project using pipenv (see Readme):

1. Run:

   scrapy crawl il_commerce -O test_output.csv

2. Monitor the stdout and ensure that the crawl proceeds without raising any errors. Pay attention to the final status report from scrapy.

3. Inspect test_output.csv to ensure the data looks valid. I suggest taking a cursory look at the target webpage and clicking through to a few of the meeting detail pages in order to spot check the data.

Are there any smells or added technical debt to note?

• I set the query params in our target URL to return a page with all meetings scheduled over the next 32 days. This choice was a bit arbitrary on my part. As a new maintainer of this repo, it's a bit unclear to me if we have a general timeframe we like to target. To my mind, a month of meeting data seemed reasonable to me. Happy to adjust this in response to PR feedback.
