Combine "Install" and "Implementations"

[jessicaschilling]

Initial commit for review/discussion.
Revises implementations section to a single install section and adjusts
headers accordingly. Rearranges sections. Note we'll have to modify
headers on blog if we go this route.
ref #293

The install panel feels more scannable than the layout that's currently live. Given that — and the usefulness of the captions that accompany each implementation — do you think it'd be better to link *here *from the top nav, rather than to the (still not great) install page on the docs site?

Here are some visual adjustments i think might be a further improvement …

• Reflow into two columns, to shorten line lengths and make the layout compact (my layout is super rough)
• Remove the borders
• Change the implementation labels to the #6acad1 green link color
• Use the current caption styling for the supporting text (16px @.6 alpha) (alternatively, keep the size at 18, but try the .6 alpha fill)
• Change the IPFS Desktop text link in the top caption to #6acad1
• Increase the contrast between the Companion callout image and the page background (eg by adjusting the image background ... don't stroke or shadow)
• Use a different image to represent desktop, such as a crop of the peers or status pages

Why are we opening just this instance of the link on a new tab?

[jessicaschilling]

I'm still thinking that anything that goes off-site should open in a new tab.

@ericronne -- Do you mind having another look? Incorporated most of your edits, but the text screen opacity made things a little illegible. Thanks!

@jessicaschilling i made some adjustments, lmk if they make any sense to you 🙏!

• Removed the stars. Unless we can dim them, they really impede readability.
• Unlinked the description text (which struck me as a non-intuitive behavior), so that only the h4label and the thumbnails link
• Colored the descriptions with a lighter gray than the current site style specifies
• Changed the text-hover to underlined, to better align with styling for other text links on the page. Note: the style still doesn't match perfectly. Other links on the page apply a border-bottom, which misbehaved when i attempted in this context.

@ericronne Thanks! These all LGTM. Sad to lose the stars, but you're correct on legibility, and since we're getting close to reworking this site as a whole, this as a fix seems fine. And good call on removing the hover for the caption text ... this made sense when the items were in boxes, but less so now.

@cwaring -- can you please have a look to hopefully bless this? Would be awesome to merge this Thursday. Thanks!

I've checked this over and pushed a few tweaks to keep things tidy™ - please take a look and feel free to merge if you're happy.
