"Add" string not translated in component_method block

[ewpatton]

Describe the bug

For the clock related methods, AddYear, etc., we have the Add string hard-coded in the block definition rather than using a translation from the messages file. This makes it impossible for translators to change this text.

Affects

• Designer
• Blocks editor
• Projects Explorer
• Companion
• Compiled apps
• Buildserver
• Debugging
• Other... (please describe)

Expected behavior

The "Add" string on the clock blocks should be translatable and present in blocklyeditor/src/msg/ai_blockly/messages.json.

Steps to reproduce

1. Add a Clock component
2. Add some of the Add* blocks in the blocks workspace
3. Change the language to anything other than English and note that the Add string will never change.
