Generate complaint path URLs with clean IDs

[contolini]

We have a function to strip HTML tags like <em> out of complaint IDs before rendering them. It was erroneously being applied only to the rendered ID numbers and not also the URLs that get generated from the ID numbers.

To see the bug in action, try clicking on the complaint that appears in these search results:

https://www.consumerfinance.gov/data-research/consumer-complaints/search/?date_received_max=2023-10-12&date_received_min=2020-10-12&page=1&searchField=all&searchText=4340364&size=25&sort=created_date_desc&tab=List

See DATAP-1210

Testing

• yarn test ComplaintCard.spec.js passes
• Searching for 4340364 and clicking on the complaint in the results should no longer show <em> in the URL.
