#82105 Add Terminal Rename Command

[petevdp]

This PR fixes #82105 by registering a new command workbench.action.terminal.renameNoninteractive that allows the user to set the terminal title via an argument instead of interactively.
example usage:

{
        "key": "ctrl+t",
        "command": "workbench.action.terminal.renameWithArgs",
        "args": {
            "newName": "my new terminal name"
        }
}

The current changes acheive this, but a few things still have to be sorted out:

• I'm open to suggestions for the name.
• It seems possible to rename the terminal based on its index or even ID, if terminal IDs are exposed to the user. Would this be desirable behaviour? This would probably take the form of an optional argument index, and not changing the default behaviour.
• How should I notify the user if the desired terminal doesn't exist? I'm guessing you can just throw an error, but if there's a preferred channel or preferred error message formatting, that would be good to adhere to. edit: 231d559 deals with this, but the error formatting still might not be ideal.
• I see that there's an adjacent file called terminalCommands.ts. There are other commands similar to this one in terminalActions.ts but terminalCommands.ts obviously seems more appropriately named.

Any additional suggestions for preferred/extended functionality are welcome!

All CLA requirements met.

Doh, forgot to post this review earlier

I think renameWithArgs is the better name, interactive/non-interactive has a very specific meaning when talking about shells so this avoids clashing with that terminology.

Thanks @petevdp, sorry about the delay. The command name is now renameWithArg

Thanks @Tyriar!
And no problem, I'm in no rush!
