[BUG] Using PyPI with GitHub repository Poetry pyproject.toml results in 'NoneType' object error for format_dependencies

[d33bs]

Describe the bug

Thank you for the great efforts with this project! I noticed a bug which appears to be reoccurring or occurring similarly to #455 and #461. The error occurs when attempting to use Grayskull from a GitHub repository which leverages pyproject.toml files. Specifically (and maybe differently from the earlier issues) I'm seeing this occur with pyproject.toml files of the Poetry variety.

Please don't hesitate to let me know if I've done something out of alignment with what Grayskull expects or supports (I may just be doing things completely wrong!).

To Reproduce
Steps to reproduce the behavior:

I created a simple demonstration repository which may be found here and is referenced below: https://github.com/d33bs/test-grayskull .

1. Attempt to run grayskull pypi https://github.com/d33bs/test-grayskull
2. Witness the error:

...
File ".../python3.9/site-packages/grayskull/utils.py", line 165, in format_dependencies
    if deps_name.replace("-", "_") == name.replace("-", "_"):
AttributeError: 'NoneType' object has no attribute 'replace

Expected behavior

I'd suggest some combination of the following possible solutions:

• A more descriptive error (mentioning what is required from the project metadata).
• Documentation covering the expected fields within pyproject.toml files (if this is where the error stems from).
• A successful build based on these types of pyproject.toml files.

Environment:

• MacOS
• Python 3.9
• Poetry 1.6.1
• Grayskull 2.5.0

Hi all,
I am having the same error now. Is there any update so far? Thank you!

[marcelotrevisani]

Hey, I am in the process of fixing this and all of your suggested solutions are great!
I just don't have much time to do it all, but indeed it would be great.

Can I break down your issue into others please?
For instance, I would like to create two more issues for:

• A more descriptive error (mentioning what is required from the project metadata).
• Documentation covering the expected fields within pyproject.toml files (if this is where the error stems from).

So, at least, I can keep track of this. The last bit is related to the fix I am doing.

I am generating version 2.5.1 that should have this fix

Thanks @marcelotrevisani ! Does the fix relate to a specific PR?

[marcelotrevisani]

#503
I fixed another bug and this one as they were simple
