Ballerina TOML parser test cases are failing in Windows

[hasithaa]

Description: The following test cases are failing in Windows.

Failing with error java.lang.NumberFormatException: For input string: "sers"

• org.ballerinalang.toml.ManifestProcessorTest > testMultipleDependencies
• org.ballerinalang.toml.ManifestProcessorTest > testSingleDependencies

These two are failing because generated TOML contains \ (backslash) (from windows path) and those have to be escaped according to the TOML spec.

Failing with error expected [path/to/github.balo] but found [path\to\github.balo]

• ballerina-toml-parser-test-suite > org.ballerinalang.toml.TomlFileToManifestTest > testTomlFile
