Vote to promote @sophiewigmore to Stacks Maintainer

[ryanmoran]

@sophiewigmore has spent a lot of her recent work days learning about and building up context on stacks while working with @martyspiewak. This work should be recognized with a new maintainership role so that she can help guide our efforts to ship secure stacks.

@paketo-buildpacks/stacks-maintainers can I get a 👍 / 👎 ?

[ryanmoran]

With a super-majority approving, @sophiewigmore is now a Stacks maintainer.
