Dom Christie created

Not sure what the etiquette is here, but in the interest of fixing
#10242, I've re-implemented @jish's PR
https://github.com/zed-industries/zed/pull/10535 and have signed the CLA


Release Notes:

- Fixed `alt-shift-left` and `alt-shift-right` in the Textmate default
keybindings.
([#10242](https://github.com/zed-industries/zed/issues/10242))

TextMate keymap uses default option shift arrow selection
