[TxMt]Minor graphical bugs

I’ve noticed there are some minor graphical bugs in TextMate. I think most of these bugs are new in Big Sur.

* The icon in the toolbar (or whatever it’s called) above the file browser could use some left margin:

* The selection for the tab buttons in the About window are a bit off:

* The text in the completion dialog (triggered by some bundle command) is not centered vertically:

* The size of the completion dialog (triggered by some bundle command) doesn’t always increase to match the content:

I’ve included screenshots for each bug, I hope they show up.

I’m running TextMate 2.0.21 on macOS Big Sur 11.1.
