Resolves #390

[kravets-levko]

Hi @dhirschfeld! Thank you for contributing! I should ask you to do two things before we can proceed:

• please sign off your commits. To fix existing comits in this branch - use git rebase -i main
• please update poetry.lock file as well using poetry lock command

[dhirschfeld]

please sign off your commits

In the linked docs it says:

you can sign your commit automatically with git commit -s

...but my commits are cryptographically signed, so do I still need the Signed-off-by: footer?

[dhirschfeld]

@kravets-levko - the commits should all be signed off now...

[dhirschfeld]

ping @kravets-levko - any objections?

Hey @dhirschfeld this is a bit tangential to your PR but in case your curious: the cryptographic signing and the Signed-off-by commit text actually serve different purposes. The "verified" badge verifies that it was your computer that generated the code. Whereas the Signed-off-by header is more about legal attribution. The "verified" header is nice to have but not required by this repository. The Signed-off-by is mandatory to protect the maintainers from legal challenges if someone attempts to commit code to this repository that they weren't authorized to open-source.

Note that this PR will also close #390

Assuming this passes the automated e2e tests this looks good to merge.
