Prefer `Seek#rewind()` over `Seek#seek(SeekFrom::Start(0))`

[frewsxcv]

What it does

Suggests using the helper shortcut method, which is shorter.

Example

fn foo<T: io::Seek>(t: T) {
    t.seek(io::SeekFrom::Start(0));
}

Could be written as:

fn foo<T: io::Seek>(t: T) {
    t.rewind();
}

seems interesting...

on a second thought... maybe it'd be better to give other people this chance consider it's a good-first-issue~

@J-ZhengLi I'm still new to Rust and this would be my first contribution to clippy so would you be available for questions if I run into issues?

Sure, but I doubt if I could be anyway near as helpful as the official members lol.

@brleinad If you have any questions, you can ask me too. Or you can ask on the zulip chat.

A quick update:
I've been working on this on and off for the last two weeks but I've been pretty busy with other things so progress is slow. I might not be able to work on it until May. If anybody else is interested in taking this while I'm away here's the Zulip thread.

Is it okay if I take over this one?

[Rqnsom]

@brleinad Ping me when you continue working on this. I've prepared a draft commit (for my learning purposes) which is partially done. I can share it with you since maybe it can help you.
Edit: I'm also trying to work on beginner issues so maybe we can learn together

Thanks for that @Rqnsom! Life has been too busy in the last few weeks to work on any Rust projects 😢 so feel free to take this over. I'm sorry for the late reply.

@brleinad No worries, I feel ya!

I'll see if I can do it during the next week maybe.
