Minor content differences on TTT page between spec & Staging

Comparing content from #979 (comment)

1. Text at top of page should say:

You can get started with Scratch in a variety of ways. Click an image to try the Tutorial. You can also download a set of Activity Cards and an Educator Guide for each theme.

However, it says "a Tutorial" instead of "the Tutorial".

2. The text at the top of the page says:

You can get started with Scratch in a variety of ways. Click an image to try a Tutorial. You can also download a set of Activity Cards and an Educator Guide for each theme.

However, the bolding isn't visible in every browser. For example, it's missing in IE 11 or Edge on Win 10, but visible on an iPad + Safari or Chrome + Mac OS 10.11.

3. What's referred to in the copy as "Hide and Seek" is titled "Hide-and-Seek Game" on Staging.
   (The other tiles' content on Staging matches what's in the comment/ copy.)
