fix(nextjs): add semver to required packages in update-package-json (#35384)

## Current Behavior
When using @nx/next:build with Yarn PnP, the generated
.nx-helpers/with-nx.js requires semver at runtime, but semver is not
included in the generated package.json. This causes the application to
fail when starting in a deployed environment with the error: "Required
package: semver, Required by: /app/.nx-helpers/with-nx.js"

## Expected Behavior
The generated package.json should include semver as a dependency so that
.nx-helpers/with-nx.js can resolve it at runtime in all package manager
environments, including Yarn PnP.

## Related Issue(s)
Fixes #34095
