[test-runner] Fail to install esbuild

[jlesquembre]

After upgrading to latest node, npm and esbuild, I'm getting this error when I launch the test-runner with the esbuildPlugin:

/my/projetc/node_modules/@web/dev-server-esbuild/node_modules/esbuild/bin/esbuild:2
throw new Error(`esbuild: Failed to install correctly
^

Error: esbuild: Failed to install correctly

It's interesing, because I have esbuild installed locally:

npx esbuild --version returns 0.12.15

As a workaround, I can force the esbuild installation executing
node node_modules/@web/dev-server-esbuild/node_modules/esbuild/install.js

But I think a better solution would be if the esbuildPlugin will use the esbuild I specified in my package.json

Seems to be a bug with npm v7:
evanw/esbuild#462
npm/cli#2606
