Jetpack: Security: Plugin auto-update copy

[scottsweb]

Need to settle on a format for 'auto-update', 'autoupdate' etc

Before:

After:

With Jetpack you can choose to have your plugins auto updated with each new plugin release. You’ll get the latest security and bug fixes right away, ensuring your site stays secure.

Choose which plugins to auto-update

Please standardize hyphen usage throughout. I.e.

• For the feature label: Plugin auto-updates ... which, now that I'm looking at it is easier to read as Auto-update plugins <<< prefer this, though it will obscure the word "plugin" somewhat.

• In the description: ...have your plugins auto-updated...

• CTA: looks good 👍

Checked in with @benhuberman on this, BTW, and he's onboard with using the hyphen.
