[Accessibility] Localization of "{{ model.value }} posts" string in bar-chart.component.html

[kivuvarosekivuvan]

Summary

Describe the bug

The string "{{ model.value }} posts" on line 14 in the bar-chart.component.html file needs to be localized to support multiple languages.

To Reproduce

1. Navigate to the apps/web-mzima-client/src/app/activity/bar-chart/bar-chart.component.html file.
2. Locate the following code block on line 14:

   <span class="chart__tooltip">{{ model.value }} posts</span>

Expected behavior

The "{{ model.value }} posts" 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 bar-chart.component.html file, replace the hardcoded "{{ model.value }} posts" string with a translation key (something like., {{ 'ACTIVITY.BAR_CHART_TOOLTIP' | translate:{ value: model.value } }}).
