Confirmed by Tom Bricker on his site. Its staying.
"Although Season of the Force ends on May 11, “Shadows of Memory: A Skywalker Saga” is expected to continue indefinitely in Star Wars: Galaxy’s Edge throughout 2025 and beyond. Check Disneyland.com or the Disneyland app for showtimes."
Also they have an alternative overlay of the nightly fireworks, "Fire of the Rising Moon" which is also staying. GE, as you may recall is in DL Park. Quote below from a question to him on his site.
"Both the shows are permanent. “Fire of the Rising Moons” started last year during Season of the Force and has continued every night there’s been fireworks since (well, except maybe New Year’s Eve–not sure if there was a version for that)."
