bugfix(PageHeader): Use font-weight initial to match the styled component styling

[jonrohan]

It was brought up in https://github.com/orgs/community/discussions/154025 that our commit headers were looking thin. Upon investigation I found that the old style had font-weight: initial;

react/packages/react/src/PageHeader/PageHeader.tsx

Line 740 in eb134ce

fontWeight: 'initial',

And the new style had a primitives variable.

react/packages/react/src/PageHeader/PageHeader.module.css

Line 232 in eb134ce

font-weight:var(--base-text-weight-light);

Changelog

@jonrohan is there a good VRT test we could add for this or is it already included?

Included with this

expect(awaitpage.screenshot()).toMatchSnapshot(`PageHeader.With Description Slot.${theme}.png`)

Surprised it wasn't caught, maybe cause the change is too subtle?
