[Bug] `--include` flag does not handle space separated globs

### Product and version

CLI 1.0.0

### Rule or diagnostic ID

_No response_

### Steps to reproduce

Reproduction: https://github.com/samcarswell/roslynator-fix-include-bug-repro

```bash
roslynator analyze ./TestSolution.sln --include 'ProjectA/MyClass.cs ProjectB/AnotherClass.cs'
```

### Actual behavior

```bash
git clone https://github.com/samcarswell/roslynator-fix-include-bug-repro.git
cd roslynator-fix-include-bug-repro
roslynator analyze ./TestSolution.sln --include 'ProjectA/MyClass.cs ProjectB/AnotherClass.cs'
```

Outputs:

### Expected behavior

I would expect the combined diagnostics from both files. If ran independently they produce the expected results:

```bash
roslynator analyze ./TestSolution.sln --include 'ProjectA/MyClass.cs'
```
produces:

### Exception messages and stack traces

```shell

```

Start by reproducing the reported command with the linked roslynator-fix-include-bug-repro project, then trace the CLI handling of the --include argument and its space-separated glob matching. Done means a single command including both paths reports the combined diagnostics shown in the issue, while each individual path continues to work.
