(🐞) `poetry install` keeps installing things that are already installed, when they were previously a git dependency

• Poetry version: 1.2.2
• Python version: 3.10
• OS version and name: Windows 10 / wsl Ubuntu 22.04
• pyproject.toml:

[tool.poetry]
name = "poetry-test"
version = "0.1.0"
description = ""
authors = [""]

[tool.poetry.dependencies]
python = "^3.10"
pendulum = { git = "https://github.com/sdispater/pendulum.git", rev = "9d06ff3c9805869ccfc4163172b658482ec50087" }
#pendulum = "^2"

• [🚀] I am on the latest stable Poetry version, installed using a recommended method.
• [🚀] I have searched the issues of this repo and believe that this is not a duplicate.
• [🚀] I have consulted the FAQ and blog for any relevant entries or release notes.
• [🚀] If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

What The Glitch❓❓❓❓

• Updating pendulum (2.1.2 9d06ff3 -> 2.1.2)

Start with the supplied pyproject.toml and reproduce the sequence of poetry update, changing pendulum from the git revision to ^2, and poetry install. Trace how the lock file records the dependency source and how install compares the installed package; done means poetry install does not update pendulum when the installed version already matches the lock file.
