unexpected --prompt arg in conda create

[Well2333]

• I have searched the issue tracker and believe that this is not a duplicate.

Make sure you run commands with -v flag before pasting the output.

Steps to reproduce

Following the approach in the documentation, I chose to use conda as the virtual environment by running following commands

pdm config venv.backend conda

and then install my project

pdm install

Actual behavior

(base) PS C:\github\VoiceS> pdm install -v

Expected behavior

arg --prompt is not available in miniconda3(documentation) which scripts is using now

简单概括一下
在使用 conda 作为虚拟环境的时候 pdm install 依然在创建环境时添加了 --prompt 作为参数，在 miniconda 的文档中可用看到 --prompt 并不是 conda 支持的参数，因此出现了错误。

prompt is managed by conda and seems difficult to change, so perhaps we should just ignore venv.prompt when using conda?
