fix: update frontend-build to fix install issues

Earlier versions of @openedx/frontend-build used on older version of
'sharp', which caused intermittent installation issues. The version of
'sharp' was updated in @openedx/frontend-build to fix these issues, so
the frontend-build version can be updated here, to fix the issues in
this project too. See
openedx/frontend-build#664 and
openedx/frontend-build#665 for more information.

The frontend-build dependency was updated by:

```
npm install --package-lock-only @openedx/frontend-build
```
