fix(fonts): correct width of \cong glyph, fix \boldsymbol{\cong}

[edemaine]

This PR is currently based on #2866 for build purposes. I'll rebase once #2866 is merged. Rebased.

What is the previous behavior before this PR?
\cong had the default advanceWidth of 1000

What is the new behavior after this PR?
\cong has the correct advanceWidth, matching = that it's based on (and many other binary operators).

Fixes #2199

Hmm, there seems to be something wrong with the fonts now: the space has gotten bigger:

@ylemkimon Any ideas? I thought the fonts were maybe not updated, but I see you just updated them.

Update: I think the SetRBearing needs to be a bunch smaller than the width... hmm...

[ylemkimon]

I wonder we should fix the date of fonts to a specific date in the past. Currently, a change in a font requires updating all the fonts.

(done in #3370)

I found a fix. Patch incoming.

Here's a screenshot of the fixed version:

x\cong y\\
x = y \\
x \boldsymbol {\cong} y \\
x \boldsymbol {=} y \\

@ylemkimon I updated this to use the new font versioning. Would you be able to review it (again)?

Here's a demo from the Netlify build:
