Fix boolean flags not being parsed as bools and thus consuming the input argument if it is given last

[Qluxzz]

When trying to generate a types file by having the input argument last, it is consumed by the flag since the BOOLEAN_FLAGS array items are camel cased but the arguments are kebab case, even though camel case expansion is true.

Example:
npx openapi-typescript --enum-values openapi.json

Here --enum-values treats the following openapi.json as a string value and then the input variable is never set, so we're stuck waiting for stdin.

npx openapi-typescript --enumValues openapi.json

Now we match the flag defined in the boolean flags array and openapi.json is correctly set as input rather than the value of --enum-values.

By changing the casing of all flags in the boolean flags array these are now parsed correctly as bools and the file argument is no longer treated as a string value for the previous flag.

Seems like a decent change. Would you please add some tests capturing the old failing behavior and demonstrating the new correct behavior?

[Qluxzz]

I've added two tests based on two existing snapshot tests which were using a kebab cased boolean flag, and swapped the order on the arguments so the input file is last in both of them.

Without the fix these tests timed out waiting for stdin and failed after we hit the timeout.

With the fix they are now generated as expected.
