refactor: Remove the “Try/Catch” block found in the EnvLoader type

[MrDave1999]

The purpose of PR is to remove this Try/Catch block:

dotenv.core/src/Loader/EnvLoader.HelperMethods.cs

Lines 69 to 73 in d6139e5

	try
	{
	_parser.Parse(source);
	}
	catch (ParserException) { }

This Try/Catch block is bad for two reasons:

• The real exception thrown is being hidden and absolutely nothing is done when the exception is caught.
  This only affects the readability of the code. It is not clear what this code does at first glance.
• It is not efficient. For example, if you read seven .env files and they all have a parse error, it will throw seven exceptions only to be caught and do nothing. This makes no sense, it wastes resources unnecessarily and is slower.

The real reason why this Try/Catch block was added was so as not to interrupt the execution flow of the .env file loader.
