Poetry dependency names not case insensitive

[h3llrais3r]

• [x ] I am on the latest Poetry version.
• [x ] I have searched the issues of this repo and believe that this is not a duplicate.
• [ x] If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Windows 10
• Poetry version: 1.1.11
• Link of a Gist with the contents of your pyproject.toml file: https://github.com/h3llrais3r/Auto-Subliminal/blob/development/pyproject.toml

Issue

Pyproject is already containing the dependency in ´[tool.poetry.dependencies]´: gitpython = "3.1.18"
This has been added manually, because I migrated from requirements.txt to pyproject.toml.
When updating the version with poetry add gitpython@3.1.20 it writes a new entry to the [tool.poetry.dependencies]: GitPython = "3.1.20" which causes poetry to think there are 2 versions required:
Poetry fails with error:

$ poetry add gitpython@3.1.20 -vvv
Using virtualenv: C:\Tools\GitHub\Auto-Subliminal\.venv
PyPI: No release information found for gitpython-2.1.2, skipping
PyPI: 1 packages found for gitpython 3.1.20

  Because autosubliminal depends on both gitpython (3.1.18) and GitPython (3.1.20), version solving failed.

The casing is also not normalized with the poetry init command - when interactively adding dependencies there, the dependencies get directly written with the case as entered, but later adding dependencies with poetry add will normalize the case - leading again to this issue.

This has since been fixed by #5700, which was released in 1.2.0b2.
