Issue (#355 (comment))

In the tabulate library, the github format did not properly handle multiline text.
If you passed tabulate data cells containing multiline text and used the maxcolwidths parameter to truncate text, the result was incorrect because the github format was not included in the list of formats that support multiline text processing.

Solution

The issue was that the github format was not added to the multiline_formats dictionary, which defines the formats that support multiline text.
The solution was simple: just add "github": "github" to this dictionary.

After our fix, the github format now correctly processes multiline text, just like other supported formats such as fancy_outline.
