Update README.md

[ed-software]

This change adds a reference to the library react-material-symbols, a library that wraps the official font-based API into a React first API.

If there is any reason why this library should not be listed here, I would love to hear feedback.

Material Symbols are for the whole web platform (and OS platforms). React libs fall under the web umbrella along with Vue, Svelte, Riot, Angular, Lit, Preact, Ember, Solid, Ionic, Stencil, Alpine, Aurelia, etc etc etc. None of those are crying for attention on the readme...

This kind of promotion creates tunnel-vision within the developer community and unintentionally creates artificial demand for React. And it creates the illusion of a lack of other options. Let people using React find React solutions. Let's stop giving React special treatment and keep the web neutral.
