skip_macro_invocations: Cannot configure from `rustfmt.toml`

[DCNick3]

skip_macro_invocations option doesn't parse as documented.

Writing skip_macro_invocations=["*", "println"] in rustfmt.toml leads to this error:

Error: Decoding config file failed:
unknown variant `*`, expected `Name` or `All`
in `skip_macro_invocations`

Please check your config file.

It seems that parsing rules are not what is actually designed (* or some name), but more like tagged serde enum. These config files work:

[[skip_macro_invocations]]
Name="aboba"

skip_macro_invocations = ["All"]

It also seems that there is some difference in behaviour between 1.5.2-stable and 1.6.0-nightly (0ab38e9 2023-07-03) (the posted example configs only work on nightly)

Thanks for a swift fix!
