Add options for json and jsonl ouputs

[ansereb]

Currently presented option json is not working with latest nuclei version. Seems like it is deleted from CLI and i receive following error when using this action:

uses: projectdiscovery/nuclei-action@main
with:
   target: https://example.com
   json: true

/opt/hostedtoolcache/nuclei/3.6.1/x64/nuclei -target https://example.com -se=nuclei.sarif -o=nuclei.log -json -irr
flag provided but not defined: -json
Error: The process '/opt/hostedtoolcache/nuclei/3.6.1/x64/nuclei' failed with exit code 2

I decided to not touch current option json and added two new options json-export and jsonl-export by analogy with sarif-export
