Update Language in the Terms of Use to Reflect Current Capabilities of the Platform

# 💡 Summary #

The first sentence of the Crossfeed Terms of Use begins "Crossfeed is a free, self-service tool offered by the Department of Homeland Security …" Anna suggested to us that the use of the term "self-service" may be misleading. The second paragraph also refers to functionality that may have been dropped

## Motivation and context ##

To ensure the language in the T&C reflects the current capabilities of the platform

## Implementation notes ##

- Review the current Terms of Use to validate that only current functionality is addressed in the summary paragraph
- Confirm that the terms meet CISA's expectations and requirements of current and future users
- Edit the Terms of Use accordingly

## Acceptance criteria ##

The Terms of Use have been updated
