[Accessibility] Localization of "This is the single point tooltip template" string in activity-timeline.component.html

[kivuvarosekivuvan]

Summary

Describe the bug

The string "This is the single point tooltip template" on line 23 in the activity-timeline.component.html file needs to be localized to support multiple languages.

To Reproduce

1. Navigate to the apps/web-mzima-client/src/app/activity/activity-timeline/activity-timeline.component.html file.
2. Locate the following code block on line 23:

<ng-template #tooltipTemplate let-model="model">
  This is the single point tooltip template
  <pre>{{ model | json }}</pre>
</ng-template>

Expected behavior

The "This is the single point tooltip template" string should be localized and retrieved from a translation file or service, so that it can be displayed in the user's preferred language.

How to solve

1. In the activity-timeline.component.html file, replace the hardcoded "This is the single point tooltip template" string with a translation key (something like., {{ 'ACTIVITY.TOOLTIP_TEMPLATE' | translate }}).
