fix: update Wikipedia dataset config from 20220301.en to 20231101.en

[kukudan]

Problem

The Wikipedia dataset config 20220301.en referenced in Lesson 09 (Data Management) Step 3 no longer exists. Running the code as written produces:

ValueError: BuilderConfig '20220301.en' not found. Available: ['20231101.ab', '20231101.ace', ..., '20231101.en', ...]

The dataset has been re-exported with the 20231101 snapshot, making the 20220301 config unavailable.

Fix

Updated the config from 20220301.en to 20231101.en in:

• phases/00-setup-and-tooling/09-data-management/docs/en.md (line 60)

Verification

Tested with datasets==4.8.5 and the updated config loads successfully:

from datasets import load_dataset
dataset = load_dataset("wikimedia/wikipedia", "20231101.en", split="train", streaming=True)
for i, example in enumerate(dataset):
    print(example["title"])
    if i >= 4:
        break

Add language tag to code block.

As per coding guidelines, every fenced code block needs a language tag. This .gitignore example should have a language tag such as text or gitignore.
