github: use envinfo for getting versions in issue reports

[agilgur5]

Description

• replace the version list with a copy+paste this envinfo command,
  copy back the output
  • uses a modified, shortened variant of something being used
    successfully downstream in TSDX: jaredpalmer/tsdx@349f299
• this should make reporting versions zero-effort and thereby
  significantly decrease non-reporting by making the hard thing easy
  • personally have experienced issues that didn't report but version
    was very relevant to the issue
  • also some folks report "latest" or used carets, which lack posterity
    or are confusing

Modified, shortened variant of jaredpalmer/tsdx#820

Output Example

It looks like this when running in TSDX for example:

$ npx envinfo --npmPackages typescript,rollup,rollup-plugin-typescript2
npx: installed 1 in 0.951s

  npmPackages:
    rollup: ^1.32.1 => 1.32.1 
    rollup-plugin-typescript2: ^0.26.0 => 0.26.0 
    typescript: ^3.7.3 => 3.7.3
