_PROXY environment and setting not honoured since 1.1.1

[lcrockett]

Describe the bug

Since version 1.1.1 PROXY environment variables are not honoured anymore. Referring to HTTP_PROXY and HTTPS_PROXY. This blocks the LS from downloading schema's. Setting a proxy via the settings in +1.1.1 does not work either. Due to a corporate firewall this prevents schema downloading functionality in +1.1.1.

Expected Behavior

I would expect either that the PROXY environment variables or the proxy settings would work.

Current Behavior

The error popping up in +1.1.1 when downloading schema's is Unable to load schema from 'https://json.schemastore.org/pre-commit-config.json': connect ECONNREFUSED 20.42.128.105:443

Steps to Reproduce

1. Use settings block below
2. Ensure LS version is +1.1.1
3. Ensure a file is opened that matches one of the listings in the settings block (for instance: .pre-commit-config.yaml)
4. The error should pop up

Environment

• Windows
• Mac
• [X ] Linux
• other (please specify)

NVIM v0.6.0-dev+589-gc0efe49e7 @ Ubuntu 20.04 LTS

Additional information

Could this perhaps be cause by this ?
