🐞 Describe the bug
I am not currently on the latest but I've checked the code and this particular part of the script was not changed in the latest version. The renumber tool previously allowed to renumber using letters. This is especially useful for grids as one direction typically has numbers and the other letters. It seems there was an update at the end of last year that forces integer usage only (see screenshot). This would also exclude decimal usage. I believe there is a another issue logged for the renumber tool with a comment in there about future plans for a reworking of this tool so I wanted to make sure this issue would be included in that if that was the case.

♻️ To Reproduce
- Start Renumber Tool
- Select any of the options
- Enter any non-integer value (Letters or decimals)
- Error immediately appears.
⏲️ Expected behavior
Previous to this update (sometime in December 2025), any input was allowed and the last character would increment up. I would expect that behavior to have continued.
