fix: escape resource names before using them as type names

[LinusBolls]

my openapi schema contains the following declaration, this is auto-generated and i don't have control over it:

"ResponseEnvelopeFoo[]": {
    "type": "object",
    "properties": {
        "status": { "type": "string", "enum": ["OK", "ERROR"] },
        "httpCode": { "type": "integer", "format": "int32" },
        "data": {
            "type": "array",
            "items": { "$ref": "#/components/schemas/Foo" }
        },
        "error": { "$ref": "#/components/schemas/ErrorDetails" }
    }
}

this gets parsed as this:

export type ResponseEnvelopeFoo[] = Components.Schemas.ResponseEnvelopeFoo;

which is of course invalid typescript syntax and breaks my build.

this pr fixes this by escaping the names of openapi resources before using them as type names.
