Application is referencing nonexistent file ktc-tagmanager.js

[Lahvac]

Describe the bug
The application shows 404 in browser console for file _content/Kentico.Xperience.TagManager/js/ktc-tagmanager.js

The file was removed in commit 49eb5ba but the scritp tag pointing to this location is still rendered by https://github.com/Kentico/xperience-by-kentico-tag-manager/blob/main/src/Kentico.Xperience.TagManager/Rendering/CodeSnippetTagHelperComponent.cs

To Reproduce
Steps to reproduce the behavior:

1. Install Kentico.Xperience.TagManager 3.0 or later
2. run the app
3. Open browser console on any page
4. It contains the 404 error

Expected behavior
The file was removed in commit 49eb5ba but the scritp tag pointing to this location is still rendered by https://github.com/Kentico/xperience-by-kentico-tag-manager/blob/main/src/Kentico.Xperience.TagManager/Rendering/CodeSnippetTagHelperComponent.cs

The file should either be provided by the nuget or the script tag should not be rendered.

Library Version
3.0.0-3.1.0

I believe the Kentico.Xperience.TagManager.csproj has a copy/pasted line that is incorrect.

BeforeTargets="NpmBuildClient" should be BeforeTargets="NpmBuildHelpScript"

After this change, someone needs to validate that a Release build creates a ktc-tagmanager.js in the wwwroot folder of the build output and that file is included in the generated NuGet package.
