Update smoke-test.yml

[astronomerritt]

Fixes #101.

I already did this for the unit tests but didn't fix the smoke tests. Essentially we need to make sure that the workflow runs pip install -e .[dev] with the -e so that the repo's directory structure is maintained. If we don't include the -e then the unit tests can't find the testing database.

I don't know why installing without the editable environment flag changes the directory structure from that of the repo and I haven't been able to find out why. Yet.

Review Checklist for Source Code Changes

• Does pip install still work?
• Have you written a unit test for any new functions?
• Do all the units tests run successfully?
• Does adler run successfully on a test set of input files/databases?
• Have you used black on the files you have updated to confirm python programming style guide enforcement?
