If you did IB, you may have heard of Schrodinger and Bohr because of their involvement in quantum mechanics and the modelling of the atom model. I'd be shocked if you learned about Wigner for example.

Noether's theorem is a much more difficult result to teach high school students, because you do need some mathematical maturity before learning it. In the UK, you're taught it in a second year undergraduate course in classical mechanics. So it is not an oversight.

Also people here seem to be overstating the influence of Noether as a physicist. Yes, her theorem is a profound result in physics but the majority of her contributions were in pure mathematics.
