Problem

As a developer, I'd like to add an argument option to align text content for elements st.markdown, st.caption, and st.text. The available options of the alignment will be left (default option), center, right, and justify.

Solution

MVP:

>>> st.markdown('Lorem ipsum dolor sit amet...', align_text='left') # Default

>>> st.markdown('Lorem ipsum dolor sit amet...', align_text='center')

>>> st.markdown('Lorem ipsum dolor sit amet...', align_text='right')

>>> st.markdown('Lorem ipsum dolor sit amet...', align_text='justify')

Possible additions: Add kwargs to the text elements for more flexible options input.
