Tooltip - revisit text alignment & fix svg color

[thrbnhrtmnn]

From the Merge- and Review-Session on 26.09. a few open/additional topics for the #118 needs to be followed:

ACs

• The Text-alignment should be reviewed by design and a decision needs to be made > Decision: Left-Alignment
• The Text-alignment needs to be changed in design to left-alignment
• The Text-alignment decision also needs to be implemented on the code side > left-alignment

As discussed in todays review- and merge-session we also added the following requirements:

• SVG needs to have the same colour as the tooltip fill and this also needs to be changed when we switch to light/dark mode
• We also need a variant that shows the tooltip on click

We decided to close this, as we already have a full refactoring of the whole tooltip planned: see #461
