docs: fix broken relative links in distillation and model list docs

[evanclan]

Summary

Fixes three relative markdown links that fail the repo link checker (reported in #18103). Each file already had a correct sibling link for the same target; this PR aligns the broken references with those paths.

Problem

From docs/version2.x/ppocr/model_compress/knowledge_distillation.{md,en.md}, the first distillation_model.py link used ../../ppocr/..., which resolves to docs/version2.x/ppocr/modeling/... (non-existent). The same pages link the file correctly later with ../../../../ppocr/modeling/architectures/distillation_model.py.

In docs/version2.x/ppocr/model_list.md, the ch_ppocr_mobile_v2.0_cls config link used ../../../../configs/cls/cls_mv3.yml (one ../ too many, resolving outside the repo). The slim variant on the preceding row already uses ../../../configs/cls/cls_mv3.yml.

Solution

• knowledge_distillation.md / .en.md: change the early distillation_model.py link to ../../../../ppocr/modeling/architectures/distillation_model.py.
• model_list.md: change the ch_ppocr_mobile_v2.0_cls config link to ../../../configs/cls/cls_mv3.yml.

Out of scope

• External 404s (BOS model tarballs, PaddleSlim anchors, etc.) from the same link-check report.
• Other ../../../../configs/... links under model_train/ subdirs — those paths are depth-correct for their directory.

Test plan

• realpath from each doc directory confirms all three links resolve to ppocr/modeling/architectures/distillation_model.py and configs/cls/cls_mv3.yml.
• CI link checker on the next scheduled run.
