MDL-53632 competency: Consistently use the terms frameworks, plans, ...

- Templates: 'Learning plan templates'
- Plans: 'Learning plans'
- Frameworks: 'Competency frameworks'

When the context, or sentence, is already stating that we are talking
about 'learning plans' or 'competencies', it may sound redundant to
repeat those terms, therefore we can simply refer to 'Templates',
'Plans', and 'Frameworks'.
