[BUG] Process monitor adds XML when format is custom

[DmitrySenin]

Describe the bug
Log Monitor wraps log lines in XML if the format is custom

To Reproduce
Steps to reproduce the behavior: Run LogMonitor against a process logging something to stdout
Result:
<Log><Source>Process</Source><LogEntry><Logline>{\"timestamp\":\"2024-05-03T14:55:51.032Z\",\"level\":\"DEBUG\",\"class\":\"Microsoft.AspNetCore.Server.Kestrel.Connections\",\"message\":\"Connection id \\\"0HN3BFISO209V\\\" accepted.\"}</Logline></LogEntry></Log>

Expected behavior
if custom format is enabled then the output of the process should be logged as-is
