refactor: replace typography with text component in signature request original component

[Devin-Apps]

Description

This pull request migrates the Typography component to the Text component in the signature-request-original.component.js file. The reason for this change is to align with the updated design specifications and improve the consistency of the codebase. The improvement includes replacing the old Typography component with the new Text component, ensuring the correct usage of TextVariant and other related enums.

See comment just need to re-arrange component imports

[georgewrmarshall]

We should be respecting environment tags ///: BEGIN:ONLY_INCLUDE_IF(build-mmi) and order of imports. Place the Text component import back inside of the ///: BEGIN:ONLY_INCLUDE_IF(build-mmi) tag

Suggested change

	Text,
	///: BEGIN:ONLY_INCLUDE_IF(build-mmi)
	Box,
	Icon,
	IconName,
	///: BEGIN:ONLY_INCLUDE_IF(build-mmi)
	Box,
	Icon,
	IconName,
	Text,
