Subject: [PATCH] trim content of `INSTALLER` file (#14488)

<!--
Thank you for contributing to uv! To help us out with reviewing, please

- Does this pull request include references to any relevant issues?
-->

## Summary

We are using UV as a library and `installer()` returned `"pip\n"`. The
packages got installed by the pip package manager and not by UV. pip
seems to add a new line to the `INSTALLER` file and UV does not.
