Conda Installation Safety Error - Size does not match reported size

## Describe the issue
I get an error when I try to install ipympl using conda as part of a python 3.11 environment.
```shell
SafetyError: The package for ipympl located at C:\Users\andrew.mole\AppData\Local\miniforge3\pkgs\ipympl-0.9.4-pyhd8ed1ab_0
appears to be corrupted. The path 'etc/jupyter/labconfig/page_config.json'
has an incorrect size.
reported size: 28 bytes
actual size: 30 bytes
```
## Versions

Start by reproducing the conda installation with the reported Python 3.11.9, ipympl 0.9.4, and Jupyter versions, then inspect etc/jupyter/labconfig/page_config.json and the package's reported metadata. Compare the reported and actual file sizes; done means the cause is documented or the package installs without the SafetyError.
