log_device.rbs issues

[sbeckeriv]

Dearest maintainer,

I am reading over https://github.com/ruby/rbs/blob/master/stdlib/logger/log_device.rbs#L15 this line here.

def reopen: (?logdev log) -> self

Is this parameter valid syntax? I would expect it to be Logdev.

Second I am unsure what Logdev is. I think based off the comment https://github.com/ruby/logger/blob/master/lib/logger.rb#L405

def reopen: (String | IO | nil) -> self

might make more sense but I am unsure. I am aslo not 100% on the correct syntax. I can make the edits if this is correct.

Thank you for you work and time,

Dictated but not reviewed,
Becker
