Library import to robot failing when python3.11 used

There is a error during importing library on python3.11:
```
[ ERROR ] Error in library 'RemoteSwingLibrary': Adding keyword 'system_exit' failed: Calling dynamic method 'get_keyword_arguments' failed: AttributeError: module 'inspect' has no attribute 'getargspec'
[ ERROR ] Error in library 'RemoteSwingLibrary': Adding keyword 'start_application' failed: Calling dynamic method 'get_keyword_arguments' failed: AttributeError: module 'inspect' has no attribute 'getargspec'
[ ERROR ] Error in library 'RemoteSwingLibrary': Adding keyword 'application_started' failed: Calling dynamic method 'get_keyword_arguments' failed: AttributeError: module 'inspect' has no attribute 'getargspec'
[ ERROR ] Error in library 'RemoteSwingLibrary': Adding keyword 'switch_to_application' failed: Calling dynamic method 'get_keyword_arguments' failed: AttributeError: module 'inspect' has no attribute 'getargspec'
[ ERROR ] Error in library 'RemoteSwingLibrary': Adding keyword 'ensure_application_should_close' failed: Calling dynamic method 'get_keyword_arguments' failed: AttributeError: module 'inspect' has no attribute 'getargspec'
[ ERROR ] Error in library 'RemoteSwingLibrary': Adding keyword 'log_java_system_properties' failed: Calling dynamic method 'get_keyword_arguments' failed: AttributeError: module 'inspect' has no attribute 'getargspec'
[ ERROR ] Error in library 'RemoteSwingLibrary': Adding keyword 'set_java_tool_options' failed: Calling dynamic method 'get_keyword_arguments' failed: AttributeError: module 'inspect' has no attribute 'getargspec'
[ ERROR ] Error in library 'RemoteSwingLibrary': Adding keyword 'reinitiate' failed: Calling dynamic method 'get_keyword_arguments' failed: AttributeError: module 'inspect' has no attribute 'getargspec'
```
It is because of:
```
def _get_args(self, method_name):
spec = inspect.getargspec(getattr(self, method_name))
args = spec[0][1:]
if spec[3]:
for i, item in enumerate(reversed(spec[3])):
args[-i - 1] = args[-i - 1] + '=' + str(item)
if spec[1]:
args += ['*' + spec[1]]
if spec[2]:
args += ['**' + spec[2]]
return args
```

**_getargspec_** method was deprecated since python3.0 and was removed in python3.11:
https://docs.python.org/3/whatsnew/3.11.html

Start at the _get_args method shown in the issue and inspect how RemoteSwingLibrary discovers keyword arguments. Verify the behavior under Python 3.11 and confirm that importing the library registers the listed keywords without errors; no test file is named in the issue.
