feat: Bottom navigation

[shoeffner]

This PR adds the bottom navigation component as drafted by @TroyTae in #5022 (closed and in its current state no longer working) and updates it to follow the 13.0.0 material design components version.

It might still need some polishing and tests, but the basics work.
Essentially, you can build a footer with a bottom-navigation as follows:

<footer>
    <nav class="mdc-bottom-navigation">
        <button class="mdc-bottom-navigation__menu">
            <span class="material-icons mdc-bottom-navigation__icon" aria-label="Food">restaurant</span>
            <span class="mdc-bottom-navigation__label">Food</span>
        </button>
        <button class="mdc-bottom-navigation__menu">
            <span class="material-icons mdc-bottom-navigation__icon" aria-label="Drinks">local_drink</span>
            <span class="mdc-bottom-navigation__label">Drinks</span>
        </button>
        <button class="mdc-bottom-navigation__menu">
            <span class="material-icons mdc-bottom-navigation__icon" aria-label="Taxi">hail</span>
            <span class="mdc-bottom-navigation__label">Taxi</span>
        </button>
    </nav>
</footer>

To achieve:

Closes #59.

Wow this is amazing!! Good work on such a thorough implementation :D

Unfortunately though, MDC is entering a maintenance-only phase as the Material Web team focuses our efforts on Material You and the next generation of components 😔

I'd encourage you to publish this from your own repo on NPM though! I'm sure others would love to use it while they wait on the Material You bottom nav bar that we've built!

Thank you for your feedback! It's all @TroyTae's work, I only fixed some compatibility issues with the latest version.

Sorry to hear you are no longer adding missing components to MDC, I must have missed that. Thanks for pointing me to Material You :)
