[Installer] Add anchore/syft

[joshsleeper]

Add anchore/syft

We want to add anchore/syft because...

• it works consistently across Windows, Mac, and Linux.
• syft is a CLI tool from Anchore for generating SBOMs from a container or filesystem

This could be as simple as copying _example, updating the github releases
info, and doing a find and replace on a few file system path names.

How to create a webi installer

Skills required

• Basic Command Line knowledge (mkdir, mv, ls, tar, unzip, variables)

Steps

1. Clone and setup the webi packages repo

   git clone git@github.com:webinstall/packages.git
   pushd packages/
   npm install

2. Copy the example template and update with info from Official Releases:
   https://github.com/anchore/syft/releases

   rsync -av _example/ syft/

   • update syft/release.js to use the official repo
   • Learn how syft unpacks (i.e. as a single file? as a .tar.gz? as
     a .tar.gz with a folder named syft?)
   • find and replace to change the name
     • update syft/install.sh (see bat and jq as examples)
     • update syft/install.ps1 (see bat and jq as examples)
3. Needs an updated tagline and cheat sheet
   • update syft/README.md
     • official URL
     • tagline
     • Switch versions
     • description / summary
     • General pointers on usage (and perhaps "gotchas")

It's also okay to have multiple people work on part of this (i.e. the Cheat
Sheet can be done independently from the install.sh)

Hi! I would like to work on this issue. Could you please assign this to me? Also, I am a first timer, I need some guidance on the changes I need to make. Any help would be appreciated. Thanks!

@cybraia go ahead. Take a look at the video above ^^.
@joshsleeper Could you cook up the cheat sheet for this as well (you can see the README.md for just about any of the install folders for a decent example)

[joshsleeper]

alright, finally got around to getting an MR opened for this
