Tesseracts that use `polars` can fail to build on newer Macs

Description

Adding polars to tesseract_requirements.txt can lead to build failures like this on some ARM Macs (reported on M3):

#33 [run_stage 17/18] RUN _TESSERACT_IS_BUILDING=1 /tesseract/entrypoint.sh tesseract-runtime check
#33 0.950 /python-env/lib/python3.11/site-packages/polars/_cpu_check.py:271: RuntimeWarning: Missing required CPU features.
#33 0.950 
#33 0.950 The following required CPU features were not detected:
#33 0.950     avx, avx2, fma, bmi1, bmi2, lzcnt, movbe
#33 0.950 Continuing to use this version of Polars on this processor will likely result in a crash.
#33 0.950 Install `polars[rtcompat]` instead of `polars` to run Polars with better compatibility.
#33 0.950 
#33 0.950 Hint: If you are on an Apple ARM machine (e.g. M1) this is likely due to running Python under Rosetta.
#33 0.950 It is recommended to install a native version of Python that does not run under Rosetta x86-64 emulation.
#33 0.950 
#33 0.950 If you believe this warning to be a false positive, you can set the `POLARS_SKIP_CPU_CHECK` environment variable to bypass this check.

#33 0.959 Illegal instruction
#33 ERROR: process "/bin/sh -c _TESSERACT_IS_BUILDING=1 /tesseract/entrypoint.sh tesseract-runtime check" did not complete successfully: exit code: 132

It appears that polars is using instructions in their Linux ARM wheels that aren't available on those processors.

The workaround is to use polars[rtcompat] as a dependency instead.
