Description:

Currently test failures do not get annotated because the problem matcher requires that a column number be present, but go's test output does not include a column for test failures.

An example line that gets missed by the current matcher is:

/path/to/main_test.go:13: expected true but got false

The updated matcher makes the column number optional and matches the line above.

Check list:

• Mark if documentation changes are required.
• Mark if tests were added or updated to cover the changes.
