This issue is due a jline defect : https://github.com/jline/jline2/issues/281, which is fixed in Jline 2.14.4, bumping up JLine version in spark to version  >= Jline 2.14.4 will fix the issue

## How was this patch tested?
No new  UT/automation test added,  after upgrade to latest Jline version 2.14.6, manually tested spark shell features

Closes #22130 from vinodkc/br_UpgradeJLineVersion.
