pytest-cov detection assumes entry point name

[tjni]

Type: Bug

Behaviour

In python_files/vscode_pytest/init.py:

has_pytest_cov = early_config.pluginmanager.hasplugin("pytest_cov")

assumes that the plugin was loaded using its entry point name, but it can also be loaded via its module name:

[project.entry-points.pytest11]
pytest_cov = "pytest_cov.plugin"

This should be an easy fix to check for both, but I don't have time at the moment to look into how to test a patch for this in the repo, so filing an issue for this in case it is easier for someone else to address.

Thank you so much!

Steps to reproduce:

1. Disable all plugin loading in pytest using --disable-plugin-autoload
2. Load pytest-cov directly using -p pytest_cov.plugin
3. Observe that test collections fails since it thinks pytest-cov isn't available.
