Anecdata, but I lived in a low light environment for most of my life (North UK), then spend the last ~15 years in a much brighter environment (NZ). My prescription has dropped from a mid -5 to a low -4 in that time, which is a fairly large and uncommon improvement for someone middle aged. The optician put it down to where I've been living.

Decreased myopia is very common in middle-aged people. Mine went from -2 to 0 in my 40s. I did not move to New Zealand.

I know that it's common to stabilize in middle age once you stop growing, but can't find any info about it being common to reverse. Regardless, congratulations! That's a great outcome.
As I understand it, the reversion to normal vision is not caused by changing length of the eye (as you say, nobody is growing in their 40s) but rather by a degeneration of the refractive power of the materials in the eye.
