update libs for security reasons

Update libs with security issues.

Update nodejs version because one of the dependency has a restriction on nodejs>=18
https://github.com/nodejs/node-addon-api/blob/main/package.json#L484

Closes #1029

Closes #1031

I'm forcing

    "node-addon-api": "^8.1.0",
    "node-gyp-build": "^4.8.2",

and it works well.

@tbo47 you can also mark this PR with the following note at the top:

Closes #1029

Since this also fixes the issues when bcrypt is installed in a project that also uses sharp, which breaks the sharp build.

@recrsn @ncb000gt it would be great to get this reviewed + merged + published, if you have a chance!

Apart from the security concerns, it's causing bcrypt to break the builds of sharp because of the outdated node-addon-api version:

• no member named errors with node-addon-api@^5 #1029

I can confirm that in our first tests, the newer node-addon-api@8.1.0 version also works to build bcrypt.
