Fix zodiac deployment action

[fangq]

hi @MarSH-Up, I debugged the sftp action and have to do the following to fix the broken action

1. as you suggested, fork wlixcc/SFTP-Deploy-Action to NeuroJSON org solved the repo error - I have no idea why it triggers this error despite that this action is already in the Github marketplace, maybe because this is a private repo?
2. I have to regenerated the ssh private key by adding -m pem with ssh-keygen, so that the output is in the pem format (which has a header of BEGIN RSA PRIVATE KEY)
3. add the public key to authorized_keys file

ssh-keygen -m pem -t rsa -b ... -C "..."
cat id_rsa.pub >> ~/.ssh/authorized_keys

after the above 3 changes, the action now works

although the built webpage can be uploaded to zodiac, but the page is empty, you can take a look, I will create another issue on this (#20)

https://zodiac.coe.neu.edu/dev/dev_fang/

the body of the index.html file shows "You need to enable JavaScript to run this app."

please take a look and merge to your branch. after we fix the empty page problem, feel free to push it to staging.

I removed the "restart server" action - I thought the generated web page are static only, why do we need to restart?

also, I see you were exporting the private key to a file. I feel this could leak the key in the future if we are not careful.

is this restart step really necessary?
