bug: [TS SDK] `setVariable`'s parameter `isSecretIfNotExist` is incorrectly interpreted

[Tyg-g]

Describe the bug

When the parameter isSecretIfNotExist in the setVariable function is false, the created variable becomes a secret variable when it should not.

Reference: setVariable(path, value, isSecretIfNotExist?, descriptionIfNotExist?): Promise<void>
Doc: https://app.windmill.dev/tsdocs/functions/setVariable.html

To reproduce

Use the setVariable function to create a new variable.

Behavior:

OptionalisSecretIfNotExist value	Behavior
true	The variable becomes a secret
false	The variable also becomes a secret! ❗
undefined	normal variable (not a secret)

Expected behavior

The value false should produce a plain variable.

undefined and false should already behave the same: https://github.com/windmill-labs/windmill/blob/main/typescript-client/client.ts#L700
