README's training section has ill-formatted numbered list and ineffective text highlighting

[DvrkRain]

Problem: In the training section numbered list failed to render correctly. And also, text highlighting is very difficult due to confusing selection

aibolit/README.md

Lines 279 to 290 in c8a8d91

	Please notice, that if you set `TARGET_FOLDER`, your dataset files will be
	in `TARGET_FOLDER/target`.
	That is why it is necessary to
	set HOME_TRAIN_DATASET=`TARGET_FOLDER`\target\08\08-train.csv,
	HOME_TEST_DATASET =`TARGET_FOLDER`\target\08\08-test.csv
	7. If you need to set up own directory where model will be saved, set up also
	`SAVE_MODEL_FOLDER` environment variable.
	Otherwise model will be saved into
	`cloned_aibolit_path/aibolit/binary_files/model.pkl`
	8. If you need to set up own folder with Java files, use `--java_folder
	parameter`, the default value will be `scripts/target/01` of aibolit cloned
	repo

Actual render (text):

Suggestion (Numbered List): Create spaces between text or put part of text at some point in numbered list
Suggestion (Text Highlighting): Highlight all environment variables, including name and value. Use Windows (set and display) or Linux (set and display) style of taking environment variables
