Implement the new H4CC page on partnerships

[dorothyyeager]

Summary

What we are after:
We made a new page for partnership and LLC contributions in 10.3 in #3038 . This information is in many bits and pieces throughout H4CC. To stick to our content rule of information has one home, we need to go through H4CC and modify those pages to link to our new page.

Background

New page: https://www.fec.gov/help-candidates-and-committees/candidate-taking-receipts/partnership-llc-contributions/

Completion criteria

• Go through all H4CC pages to look for references to partnerships and replace with brief text and internal button link to new page. Some pages to look at:
  https://www.fec.gov/help-candidates-and-committees/taking-receipts-political-party/who-can-and-cant-contribute-party-committee/
  https://www.fec.gov/help-candidates-and-committees/candidate-taking-receipts/who-can-and-cant-contribute/

  https://www.fec.gov/help-candidates-and-committees/taking-receipts-pac/who-can-and-cant-contribute-nonconnected-pac/
• Replace links on collection pages to the pages listed below with link to new page (placed in the "who can/can't contribute" part:

  https://www.fec.gov/help-candidates-and-committees/taking-receipts-pac/contributions-nonconnected-pacs-limited-liability-companies-llcs/
• Put redirects into Wagtail for the above pages.
• Remove "continue learning" references to old partnership brochure from pages that may link to it. (See our reference guide in shared content folder)

Have replaced the links on the three collection pages and redirected those older pages to our new page. Have gone through the pages listed and taken out references to older brochure and put in internal button referring reader to new partnership page. Will review H4CC some more with fresh eyes tomorrow to ensure all references are current and pages taken down are redirected or replaced with a fresh link.

I've updated several pages to remove references to the older brochure and/or web pages, and replace with links to the new page. Nice chance to clean up a bit! I've also added the older brochure to our redirect list for our next batch of transition redirects. Work is complete so closing this ticket.
