fixed typos (#735)

1. In the first paragraph, "observability" is misspelled as
"observablity."

2. In the "Supported Destinations" section, "Traces" should be aligned
with the other columns.

3. In the "Contributing" section, "You are welcome to join" can be
improved for clarity. You can rephrase it to "Feel free to join our
active Slack Community."
