Tooltip Display Issue: Incorrect Class for Mouseenter Event

[hardik-143]

Currently, tooltips are not displaying as intended due to the use of the incorrect class for the mouseenter event on GitHub's contribution calendar. Instead of the expected class "js-calendar-graph-svg," the correct class should be "js-calendar-graph-table." This discrepancy is preventing the tooltips from appearing as expected when hovering over specific days on the calendar. Rectifying this issue by utilizing the correct class will ensure that tooltips are displayed accurately, enhancing the user experience on GitHub's contribution calendar feature.
