gdb-pretty-print not working with python < 3.9, because of removeprefix

[bitFiedler]

Description

If gdb uses python version < 3.9 the pretty printer do not work because of the missing implementation of 'removeprefix'.

This function is only available since python version 3.9.

I can reproduce this bug by using latest version of CLion 2024.3.4, because they are using python version 3.8.

Reproduction steps

try to pretty print nlohmann object.
that occurs in an exception because the string obj do not have a function called removeprefix

Expected vs. actual results

pretty print should work if python version is < 3.9

Minimal code example

Compiler and operating system

Validation
