Opening brackets causes suggestion box to appear unwanted

[ddiegow]

Describe the bug
When opening brackets for a function the suggestion box appears immediately, forcing me to cancel it every time (VSCode editor)

To Reproduce
Type a function, open brackets and the suggestion box pops up (I disabled all my extensions, enabled them one by one and the culprit seems to be the Spring Boot Tools extension)

@martinlippert I'd probably simply exclude the { from trigger chars for completion proposals... #1513 The completions shown are applicable to the block... it is just that content assist is triggered at the wrong time... The downside of this fix would be not triggering content assist automatically once typed: @Value(${... From this perspective we could probably not show bean proposals if invoked for something like {^}... not sure if this is a good idea though.

@BoykoAlex Let's remove the trigger character for now and quickly include that in the 4.29.1 fix release. We can then re-think this in more depth for the 4.30.0 cycle.

Created #1514 as a follow-up for the 4.30.0 cycle.

Fixed for 4.29.1
