Use npx command

[stevenjoezhang]

Proposed change

The build scripts in this repository heavily use ./node_modules/.bin/gulp to execute gulp commands, whereas using npx gulp can achieve the same effect and I believe it's more elegant.

We should make sure that npx will not go and download gulp but only uses the local version

When the package is installed locally npx is using the local one, as far as I know.

I know, but if it isn't it will download the newest version online. We should prevent that.

I don't think npx has a flag for that. We should then only use it in the workflows.
For the build scripts it would make more sense to migrate them to npm scripts and run it with yarn then it will only take the local one.

First, we shouldn't use npx for anything since we use yarn. The roughly equivalent command is yarn dlx.

However, the right approach here is just to let yarn resolve gulp or any other executables:

yarn run gulp ...

This just uses what we already install. This needs to be done anyway before we could switch to PNP.

Thanks @steverep for input. Your way is the right one. I'll close this PR since we want to stay with yarn and want to go the PNP route.
