[Bug]: Codecoverge --exclude doesn't allow to pass file names with commas

[gayaldassanayake]

Description

From update 6 onwards, testerina supports a new feature that allows to exclude files from the code coverage report.

The format of the command is bal test --code-coverage --excludes=<source_path1>,<source_path2>.

However, when the name of the source file that has a comma is given as a value to the --excludes flag, it splits the file name from the comma and identifies as two files.

Steps to Reproduce

1. Create a new ballerina project with tests
2. Create a source file named source,file.bal
3. Run the command bal test --test-report --code-coverage --excludes='source,file.bal' --coverage-format=xml
4. The output is as follows
