[Documentation:System] Term creation instructions (#592)

I created a new file and added instructions for usage of the
create_term.sh script to create a script. I added it to the top of the
configuration section as that is likely the first thing that the
sysadmin should be doing.

+### Creating a term
+To create a term, you should use the script 
+```
+/usr/local/submitty/sbin/create_term.sh
+```
+Follow these usage guidelines: 
+```
+Usage: create_term.sh  [-a|--amend] <term>  '<name of term>'  <start date>  <end date>
+```
+
+The term should be an abbreviated semester name like:
+```
+s24
+```
+While name of term would be a more descriptive name like "Spring 2024".
+
+The start and end date must be formatted in mm/dd/yyyy format.
+
+Use -a or --amend to amend an existing term.
+An example valid usage of this command would be:
+
+```
+create_term.sh s24 'Spring 2024' 01/09/2024 05/01/2024
+```
