app template files are not shipped with 0.6.0 pypi dist

Bug Description

When I tried to create a new app with clams develop command, it didn't work because templates were not properly packed into the 0.6.0 pypi distribution, and hence raises FileNotFoundErrors.

Reproduction steps

$ clams --version
0.6.0 (based on MMIF spec: 0.5.0)
$ clams develop -n newapp
Traceback (most recent call last):
  File "/opt/homebrew/Caskroom/miniconda/base/envs/new/bin/clams", line 8, in <module>
    sys.exit(cli())
