## Environment

**Liquibase Version**: 4.4.0

**Liquibase Integration & Version**: Maven

**Liquibase Extension(s) & Version**: None

**Database Vendor & Version**: All

**Operating System Type & Version**: Any


## Description

I am using XML changelog with <includeAll> for which path is mandatory in a zip file

```
<includeAll path="" relativeToChangelogFile="true" filter="my.XMLFilter"/>
```

I want to include all files in the directory of the changelog.
1. `<includeAll path="">` => Not working, is resolved to root of the zip archive
2. `<includeAll path=".">` => Not working, path is not normalized and ZipFileSystem does not resolve `myfolder/./` as `myfolder/`

## Steps To Reproduce

PR with unit Test to come...

## Actual Behavior
First case run into stack overflow
Second case does not find any file


## Expected/Desired Behavior
Expected behavior is to have the same behavior as regular file system


## Additional Context
Resolution can be to modify liquibase.resource.FileSystemResourceAccessor lines 237 - 239:

From 
```
                    if (path != null) {
                        basePath = basePath.resolve(path);
                    }
```
To
```
                    if (StringUtil.isNotEmpty(path)) {
                        basePath = basePath.resolve(path).normalize();
                    }
```
