Remove use of cssText in react-focus-guards

[iliana]

Description

createFocusGuard creates a <span>, then applies CSS to it using cssText. This violates Content-Security-Policy unless style-src: 'unsafe-inline' is permitted. Setting the individual properties is acceptable under a strict CSP.

@iliana I'd like to include this in the next release. Do you mind running yarn version check --interactive so everything is versioned correctly and captured in the changelog?

I'm not familiar with yarn, so I'm not sure why this doesn't work:

$ yarn version check --interactive

It seems like my yarn version is correct per the value in package.json:

$ yarn --version
4.1.0

Evidently the merge from main caused the issue, yarn doesn't seem to be able to handle that. I rebased instead.
