Updates for global site search

[patphongs]

Summary

• Resolves Reindex site results with search.gov #2991

Reindexing has already been completed on the website using search.gov and our custom indexing scripts. Followed documentation based on what was written here: https://github.com/fecgov/fec-cms/blob/develop/fec/search/management/instructions.md

The transition drawer did not exist in our search.gov interface, therefore, I removed it from the site index commands.

Impacted areas of the application

List general components of the application that this PR will affect:

• Global search on site's header

How to test

• Re-activate your account on the rebranded search.gov. If you have not logged into search.gov for more than 90 days, your account has been deactivated. You'll need to email [email protected]
• Login to search.gov and look around
• Get a fresh dump of the wagtail CMS database and update your CMS DB on your local machine.
• Follow documentation under this branch: https://github.com/fecgov/fec-cms/blob/feature/2991-global-site-search/fec/search/management/instructions.md to understand how scraping and indexing works
• Attempt to run scrape and index commands using this branch
• Take a look at the main drawer referenced in the documentation. If an index has been done, it will push it to the search.gov main drawer and it should say that it has been updated recently.

@patphongs the search.gov team said they reactivated my account on Friday but I'm not able to log in. I sent them another email and I'm waiting to hear back.
