Fix tooltip color contrast to meet WCAG standards

Updated tooltip text color for the permissions hover tooltip to improve readability. The previous color #298625 had a contrast ratio of 3.93 against background #d8f4d7, below both WCAG AA (4.0) and AAA (7.0) standards. The new color provides a contrast ratio of 7.27, ensuring better accessibility.
