65 update to use copier v7

[kefeimo]

Fixed Update to use copier v7 #65 : and Doesn't seem to be interpolating values from prompts #63

Verification

Use the same answers to copier prompts and compared to the last workable release version (copier==5.1.0, commit: 3b3315f)

• run copier copier-poetry-volttron-agent/ Example-copier7/ --vcs-ref fb4c7e2
• with the following answers to the prompt,
• Similar process, but using copier==5.1.0 and commit 3b3315f, i.e., copier copier-poetry-volttron-agent/ Example-copier5/ --vcs-ref 3b3315f
• Compare the generated templates, i.e., diff -r Example-copier5 Example-copier7 > diff_5_7.txt

Result

The result in "diff_5_7.txt" shows that all the generated files by the two versions are the same, except ".copier-answers.yml" file, which is due to using different commit

diff -r Example-copier5/.copier-answers.yml Example-copier7/.copier-answers.yml
