Findstr: ClickFix PNG palette execution + Splunk detection references

Findstr.yml

Adds an Execute use documenting a ClickFix technique reported by Daniel Messing (Vega). The victim pastes a Run-box command that uses for /r and findstr to search cached files over 400 KB under %LOCALAPPDATA% for a marker string (sSJ105) hidden in a PNG's color palette, then runs the matched command in a minimized cmd window.

Splunk detection references

Adds Splunk Security Content detection links to the Detection section of existing entries, including At, Bitsadmin, Certutil, Cmd, Mshta, Msiexec, Regsvr32, Rundll32, Schtasks, comsvcs and others, so defenders can go straight from a LOLBAS entry to a working detection.

Validation passes (schema and yamllint).

Carry forward the useful detection links from PR LOLBAS-Project#242 while avoiding the old YAML reformatting and generator script changes.

Hi @josehelps , the findstr technique does not qualify as a LOLBAS entry. Let's remove it and we can merge the Splunk references. Even though some are marked as deprecated, it may still be of use to some.

Hi @josehelps , this does not qualify as a LOLBAS. The behaviour you're describing is just finding a string occurrence in a file.
