[Adjust Rule] SIM109 - Suggest tuple instead of list

[mxr]

Desired change

• Rule(s): SIM109
• Adjustment: Suggest rewriting to a tuple instead of a list

Explanation

See rationale here

Example

This change would update the error message as follows:

- SIM109 Use 'a in [b, c]' instead of 'a == b or a == c'
+ SIM109 Use 'a in (b, c)' instead of 'a == b or a == c'
