chore: move repro steps up in issue template

[junlincc]

SUMMARY

After filing near 300 and triaged near 1000 issues in Superset repo, I found that having reproduce steps right after the 'one sentence issue description', following with Expected Results and Actual Results is more logical.

• The 'What' and 'How' should stay close, which help ticket assignee to grab the context easier
• People often forget to provide repro steps( which is the most important info) as the section was not in a prominent section.
• The info in Issue description and Expected results seem repetitive.
