Toggle between insert and overwrite/overtype mode by pressing the Insert key

Is your feature request related to a problem? Please describe.

When modifying data sets/members with fixed record lengths (and line numbers at the end of the record), users have to be conscious of how many characters they are inserting into a line, then then delete the same number of spaces. Most text editors allow users to toggle between insert and overwrite, but VS Code does not.

Describe the solution you'd like

When a user hits the Insert key, toggle between insert and overwrite mode.

Describe alternatives you've considered

An extension exists that provides this functionality: https://github.com/DrMerfy/vscode-overtype/tree/master

However, some users would prefer that this functionality be provided from Zowe Explorer.
