[i18n-activity] Change embed to isolate in example (#835)

r12a has just created a new issue for https://github.com/w3c/i18n-activity:

== Change embed to isolate in example ==
10.2.12 tts:direction
https://w3c.github.io/ttml2/index.html#style-attribute-direction

> The tts:direction style is illustrated by the following example.
```
<p> The title of the book is "<span tts:unicodeBidi="embed" tts:direction="rtl">نشاط التدويل، W3C</span>" </p>
```

It is recommended to always use isolating bidi controls, rather than embedding, since it solves many problems for RTL scripts.

Therefore we recommend an editorial change to this example, to encourage good usage: change tts:unicodeBidi="embed" to tts:unicodeBidi="isolate".
