5.4..2 support needed :-Incorrect Kibana version in plugin [elastalert]. Expected [5.4.2]; found [5.2.2]"

[nsvijay04b1]

For kibana 5.4.2 kibana, it fails with
"Plugin installation was unsuccessful due to error "Incorrect Kibana version in plugin [elastalert]. Expected [5.4.2]; found [5.2.2]"

WA:- 1) unzip elastalert-0.0.6.zip
2) replace 5.2.2 to 5.4.2 in package.json
3) zip again
4) this time, installation sucessful

But, not sure if this is okay and this plugins is built to support 5.4.2?
