[DOCUMENTATION] Missing Info and Two misspellings on Contact Matching documentation

[jimhubert]

We just had a problem with a custom duplicate rule not working for Contact Matching, the issue was that the API name of the picklist value added to the "Contact Creation Duplicate Rule" field on the Summit Events object did not match the API name of the Duplicate Rule. Highly recommend that the documentation be updated to include this information on the "Contact Matching" documentation page (https://sfdo-community-sprints.github.io/summit-events-app-documentation/docs/advanced-features/Contact-Matching/) to prevent others from having this problem.

Here is the recommended text to add to the end of the "Copy and Paste the name of your newly created duplicate rule here and save your changes" sentence: "Important: API Name of Picklist field must match the API name of the duplicate rule or else it will not work for matching."

While investigating I noticed two misspellings on this page as well: "feild" and "piclist" which should be corrected.
