[2.6.0] Single quotes parsed literally #337

Since version 2.6.0 single quotes are apparently parsed literally which leads to various issues:

foo='value with spaces' is now 'value with spaces' (was value with spaces) and is thus unquoted (as in: not surrounded by double quotes) leading to an error:

PHP Fatal error: Uncaught Dotenv\Exception\InvalidFileException: Dotenv values containing spaces must be surrounded by quotes. in /.../vendor/vlucas/phpdotenv/src/Parser.php:7

Due to this, the $ character cannot be escaped properly anymore:

• foo='$bar' is now '$bar' (was $bar)
• foo="\$bar" is \$bar
• foo="$bar" is $bar but this will lead to issues when .env is loaded e.g. in Bash which then tries to load a non-existing variable called bar
