If a text filter "Markdown" is already present the module refuses to install with an error "the markdown text filter already exists". This is happening if you use the "Markdown" module and you would also like to add "Markdown Easy". Even deinstallling "Markdown" module doesn't allow to install "Markdown Easy" as the text filter is still there.
There is no option for completely deleting a text filter (just "disabling") which doesn't solve the problem.
If "Markdown" text filter is already present, don't throw error and enable the module.
There is a workaround to circumvent this scenario: As stated in issue https://www.drupal.org/project/markdown_easy/issues/3436943 🐛 Markdown text format not created Closed: works as designed before 1.0.1 the text filter wasn't created upon enabling the module, so you can downgrade to 1.0.0 by running:
composer require 'drupal/markdown_easy:1.0.0'
afterwards enable the module, then upgrade again.

I have the feeling this MR will fundamentally break the module.
I have to agree with @bramdriesen on all of his comments. I would like to see this MR cleaned up a bit and a test added before considering this change (especially because this is a bit of an edge case and a workaround exists.)
