`.mise.toml` configuration: duplicate key `venv` in table `env`

(first time user)

Describe the bug I'm unable to configure my .mise.toml file to enable automatic virtual environment activation in my python project directory. Any action in my test directory, which solely consists of my .mise.toml file, returns the following error:

Error loading settings file: TOML parse error at line 6, column 1
  |
6 | _.python.venv = "/root/.venv" # can be absolute
  | ^
duplicate key `venv` in table `env`

To Reproduce Get started:

1. install mise using Homebrew.
2. copy the activation script into ~/.zprofile (as opposed to ~/.zshrc)

Configure python version management:

3. install the latest version of python
4. make a test directory as a test project
5. use nvim .mise.toml and paste this example from the documentation:

[tools]
python = "3.11" # [optional] will be used for the venv

[env]
_.python.venv = ".venv" # relative to this file's directory
_.python.venv = "/root/.venv" # can be absolute
_.python.venv = "{{env.HOME}}/.cache/venv/myproj" # can use templates
_.python.venv = { path = ".venv", create = true } # create the venv if it doesn't exist

6. save and exit

Expected behavior I expect a python virtual environment to be automatically created and activated.

Another .mise.toml file configuration with no environment variables does not work either. I locally install python version 3.10.14 with mise use python@3.10 and only write

[tools]
python = {version = '3.10', virtualenv = '.venv'}

but this gives

mise no venv found at: ~/repos/test/.venv                                       

To create a virtualenv manually, run:
python -m venv ~/repos/test/.venv

I expected .venv to be automatically created. I can create and activate .venv manually and it all works fine.

Nevermind--adding a line

[tools]
python = {version='3.10', virtualenv='.venv'}

[env]
_.python.venv = { path = ".venv", create = true } # create the venv if it doesn't exist

automatically creates the .venv directory. This is a temporary solution; I assume that activating it is supposed to be manual. If you access the path with the key like this

[tools]
python = '3.10'

[env]
_.python.venv = ".venv"
_.python.venv = { path = ".venv", create = true } # create the venv if it doesn't exist

it's still seen as a duplicate.
