Date like keys break taplo

[ModProg]

dates should be valid keys (https://github.com/toml-lang/toml-test/blob/main/tests/valid/key/like-date.toml#L14) but taplo reports for that valid file a bunch of errors when you run taplo lint tests/valid/key/like-date.toml.

The problem seem to be date like table names [2002-01-02] and dotted keys 2002-01-02.2024-01-03.

Might generally be a good idea to run taplo agains the official test cases on top of https://github.com/BurntSushi/toml-test
