Mixed types in array leads to warning

[miketheman]

Given a TOML key with an Array,
When using valid syntax of strings and tables,
Then a warning should not be raised.

Example:

include = [
    { path = "foo", format = "sdist" },
    "bar.md"
]

Triggers:

Cannot add value of type String to array of type InlineTable.

Desired behavior:

No trigger raised, as this is valid TOML syntax.
