Multiline inline-tables are allowed in TOML 1.1.0, but not yet supported by tomlkit

[nmay231]

Using tomlkit 0.14.0 and trying to read the following example:

# example.toml
[my_table]
key = {
   inner = 1
}

Running:

uv run python -c "import tomlkit, pathlib; tomlkit.loads(pathlib.Path('./example.toml').read_text())"

Gets the following error:

tomlkit.exceptions.EmptyKeyError: Empty key at line 3 col 7

Traceback (most recent call last):

And according to the TOML 1.1.0 spec, newlines inside of inline tables should now be supported.

Inline tables can have multiple key/value pairs on the same line, or they can be put on different lines. A terminating comma (also called trailing comma) is permitted after the last key/value pair.

Thank you for your time and effort with this package.
