Patterns are not respected on Import/Export in Rider

[andriibratanin]

Custom hightlight patterns are not saved/loaded during Import/Export of Log Patterns

IMPORT
Steps to reproduce:
Import the following Ideolog file using Rider -> Settings -> Editor -> Log Highlighting:

<State>
  <highlightingPatterns>
    <LogHighlightingPattern enabled="true" pattern="^\s*err\s*$" captureGroup="-1" action="HIGHLIGHT_LINE" fg="-39836" bold="true" italic="false" stripe="true" uuid="5bcf6a90-78f1-43a4-9a8c-375910f23b12" />
    <LogHighlightingPattern enabled="true" pattern="^\s*wrn\s*$" captureGroup="-1" action="HIGHLIGHT_LINE" fg="-6329600" bold="true" italic="false" stripe="false" uuid="3cb63bd6-2f81-4bb6-8944-0a0a674cb427" />
    <LogHighlightingPattern enabled="true" pattern="^\s*inf\s*$" captureGroup="-1" action="HIGHLIGHT_LINE" fg="-10316203" bold="false" italic="false" stripe="false" uuid="0f8ad928-941b-4ebe-8e50-ec601c49b5a7" />
  </highlightingPatterns>
  <hiddenSubstrings />
  <parsingPatterns>
	<LogParsingPattern enabled="true" name="Serilog (default)" pattern="^(\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}\.\d{3} [+-]?\d{2}:\d{2}) \[([A-Z]+)\] (.*)$" timePattern="yyyy-MM-dd HH:mm:ss.SSS XXX" linePattern="^\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}\.\d{3}" timeId="0" severityId="1" categoryId="-1" fullmatch="false" uuid="496412b0-aed0-4b48-a539-30522f90d3ce" />
  </parsingPatterns>
  <settingsVersion>9</settingsVersion>
</State>

Actual result:
You'll see the new "Serilog (default)" log template, but will not see three additional log hightlighting patterns included in the file.

EXPORT
Steps to reproduce:
Add a new or change one of three "standard" log highlighting patterns, then export any Log Pattern using "Export" button (Rider -> Settings -> Editor -> Log Highlighting).

Actual result:
You'll see that custom log highlighting patterns or changes to "standard" ones are not present in the export data (i.e. export file will include only three non-changed "standard" patterns).

Expected behaviour:
Log highlighting patterns are correctly imported/exported
