L2M TabICLv1 prior integration #166

For the integration of TabICLv1 priors in L2M the following steps are still needed:

• refer to l2m_tabicl_prior as 'L2M_better_synth' to stay aligned with our naming convention
• Check L2M description in Readme, it is long and might not be correct
• check l2m_tabicl_prior readme files
• check why l2m_tabicl_prior code is excluded in ruff.toml: "src/afabench/components/methods/discriminative/l2m/tabicl_v1_prior" This seems off
• Test dataset outputs
