Use the LinterSettings's tab size when expanding indent (#9506)

## Summary
In the `logical_lines`'s `expand_indent` , respect the
`LinterSettings::tab_size` setting instead of hardcoding the size of
tabs to 8.

Also see [this
conversation](#9266 (comment))

## Test Plan

Tested by running `cargo test`
