fix(dev/release): call conda init before conda activate

[zeroshade]

Ran into an issue when running verify-release-candidate.sh using USE_CONDA=1. Got an error specifying that we need to call conda init before conda activate base. After adding that line the verification was able to continue.

After adding this line to the verification script, I'm still seeing this in the output (but it doesn't cause any failure):

=====================================

CondaError: Run 'conda init' before 'conda deactivate'

└ Ensuring that Conda is installed...

I'm not sure we want this, doesn't conda init write to the user's bash_profile and such?
