Update Node to v14.17.2

[jsjoeio]

One of the code-server community members reached out asking if we could update the node version in code-server to 14.17.2 to fix a couple security vulnerabilities in 14.17.1

Original message:

My team is using code-server in our work and in doing a scan for vulnerabilities, we noticed that the most recent release of code-server updated the node version to 14.17.1. This resolved a lot of high severity vulnerabilities, but in doing a snyk.io scan, it detected two more high severity vulnerabilities that are resolved in Node v14.17.2.

Output from docker scan via snyk.io:

✗ High severity vulnerability found in node
Description: Privilege Escalation
Info: https://snyk.io/vuln/SNYK-UPSTREAM-NODE-1315789
Introduced through: node@14.17.1
From: node@14.17.1
Fixed in: 14.17.2

✗ High severity vulnerability found in node
Description: Out-of-bounds Read
Info: https://snyk.io/vuln/SNYK-UPSTREAM-NODE-1315790
Introduced through: node@14.17.1
From: node@14.17.1
Fixed in: 14.17.2

​In the interim, we're fine to use a fork that's bumped the version of Node, but figured it might be worth doing in the source repo as well given it would only mean doing a patch-version bump.

@jawnsy and I checked this out. Turns out the upcoming version of code-server will use Node v14.17.4 so we don't have to actually change anything ourselves.

Notes

To future self, we checked this by:

1. Downloading the release-packages artifact from CI
2. Unzipping and untarring one of the releases
3. Running ./node --version

It's technically fixed in main already so I'm going to close this (you'll know the fix is in the release when 3.11.1 comes out)
