Update Travel Pay URL

[ayush-chak]

Issue Description

We would like to update the URL for the travel pay experience before rolling out so that future changes / adding features won't impact the end user and will reduce additional complexity for our team.

Context

Our current URL/entry point is va.gov/my-health/travel-claim-status, however as we add features, the "status" part of the url is misleading. We need to update the base URL to the more generic "travel-pay"; from there we can add specific child routes to the feature application.

Impact

Notes

• Wes Rowe / MHV sitewide team

URL

Current entry point/URL: va.gov/my-health/travel-claim-status

Desired entry point/URL: va.gov/my-health/travel-pay/{child routes here}

Changing the rootUrl for the app entry requires changes in 3 repos: vets-website (manifest.json, and all tests), content-build (registry.json), and vsp-platform-revproxy (react_routes.yml).

Order for merging is vets-website, then content-build then revproxy.
