<flux:main> as a <main> tag or option to render as one / same with <flux:sidebar> and <nav>

[oMikeo]

In the spirit of Flux aiming to ensure things are accessible out of the box, I feel like <flux:main> should render a <main> tag.

Yes I could make a custom component since what <flux:main> provides is quite simple, but perhaps that is not the case in the future and I want to lean into future Flux features. Currently handling with a nested <main> tag.

 <flux:main ... >
        <main>
                ...
        </main>
</flux:main>

<flux:sidebar> is also just a <div> when , given the intended purpose, it should perhaps be a <nav> by default. Or better yet also have default aria <nav aria-label="Sidebar Navigation"> to make it distinguishable to SR users.

Just for ref <flux:navbar> is already rendered with a <nav> tag.

Adjacent thought for documentation - include guidance or links to external resources about declaring aria-labels on nav components.
