It sets `github: true` for us.

The validator no longer complains about it unless the value is different from `content=IE=edge`, see https://www.w3.org/Bugs/Public/show_bug.cgi?id=27091

Fixes #14809.
Closes #14825.

Refs #14388.

Not clear from the spec whether this is invalid per se.
But it is the current best known workaround for Firefox's unusual behavior.

Simplifies the build tooling a teeny bit.
This data file shouldn't need to be updated for v3 ever again.
This task will also be unnecessary in v4.

This reverts commit e31c2edf.

This reverts commit 25ca5131.

Big thanks to @gvas for https://github.com/axemclion/grunt-saucelabs/pull/136 ! <3

Works around #13914.

We might give it another go in the future but the stuff this breaks over the time does not justify having it enabled. The gain in size is negligible:

dist/css/bootstrap.min.css: 108.65 kB → 109.5 kB
dist/css/bootstrap-theme.min.css: 18.84 kB → 18.86 kB
docs/assets/css/docs.min.css: 20.44 kB → 20.61 kB

Will hopefully revert this reversion and land a fully-working version of UMD in v3.3.0.

Instead of our homegrown grunt/shrinkwrap.js
Fixes #13483.
New npm-shrinkwrap.json is human-readable but still in a consistent/stable format.
Should aid debugging, produce better diffs, and be less prone to merge conflicts
