Fixed issue with derive_more Display Implementations (#16298)

# Objective

- Fixed issue where `thiserror` `#[error(...)]` attributes were
improperly converted to `derive_more` `#[display(...)]` equivalents in
certain cases with a tuple struct/enum variant.

## Solution

- Used `re/#\[display\(.*\{[0-9]+\}.*\)\]/` to find occurences of using
`{0}` where `{_0}` was intended (checked for other field indexes too)and
updated accordingly.

## Testing

- `cargo check`
- CI
