Fix npm publish workflow

[gwdawson]

due to an oversight on my behalf, (#34) didn't actually fix the issue.

as you can see from the demo, without the second half of the script, if husky doesn't exist it still throws an error making the workflow fail. however, with the second half, if husky doesn't exist the command just runs echo and doesn't error

github is now throwing errors whilst trying to upload the demo (linked in slack thread):

This still is not going to work. I'd recommend that you test it in the console before.

➜  lezer-logql git:(main) test -d node_modules/husky && husky install || echo 'husky not installed... ignoring script'
zsh: command not found: husky
husky not installed... ignoring script

I'll recommend something shortly.

There's another thing that I don't like, which is that we use yarn to build the library, when we don't have a yarn.lock file, we use npm in this repo.

Please try the following:

• Go to publish-npm.yml
• replace yarn with npm instal --ignore-scripts
• replace yarn build with npm run build

Btw, github actions can be tested with https://github.com/nektos/act
