Fix for binary upload step, use bash shell rather then default sh (#86382)
This fixes the issue during upload:
```
Run # reference ends with an RC suffix
# reference ends with an RC suffix
if [[ ${GITHUB_REF_NAME} = *-rc[0-9]* ]]; then
echo "UPLOAD_CHANNEL=test" >> "$GITHUB_ENV"
fi
shell: sh -e {0}
/__w/_temp/f045f5d8-ddb.sh: 2: [[: not found
```
