taplo doesn't support files that don't end in .toml

[anguslees]

tbc, the taplo tool itself doesn't seem to support files that don't end in .toml.

$ ./taplo-linux-x86_64 --version
taplo 0.9.3
$ cat .taplo.toml 
[[rule]]
include = ["**/foo", "**/foo.toml"]
[rule.schema]
path = "<my schema>"
$ ./taplo-linux-x86_64 validate foo.toml
INFO taplo:load_config: found configuration file path="<pwd>/.taplo.toml"
INFO taplo:lint_files:collect_files: found files total=1 excluded=0 cwd="<pwd>"
$ ./taplo-linux-x86_64 validate foo
INFO taplo:load_config: found configuration file path="<pwd>/.taplo.toml"
INFO taplo:lint_files:collect_files: found files total=1 excluded=1 cwd="<pwd>"

Note excluded= values.

Schema checks work (correctly identify errors) in foo.toml, but I can't find any combination of options that makes foo get included.

(Same through both vscode extension and cli tool)
