Fix Baseline Profile Generate from GMD

[Jaehwa-Noh]

What I have done and why Change tasks use :app:generateDemoReleaseBaselineProfile. From Baseline profile documentation

Note: To generate and install the Baseline Profile from the command-line interface, run the :app:generateBaselineProfile or :app:generateVariantBaselineProfile Gradle tasks.

Used GMD from here https://github.com/android/nowinandroid/blob/211654ff16aea732cab8fd6148998c2a7293612f/benchmarks/build.gradle.kts#L48-L54

Output:

Fix #1467, fix #859
