Fix REUSE 'non-compliant' badge

[jaroslav-viravec]

I spotted that our redis-operator has REUSE 'non-compliant' badge because:

https://api.reuse.software/info/github.com/SAP/redis-operator

• there is 'APACHE-2.0' not 'Apache-2.0' as # SPDX-License-Identifier: APACHE-2.0 in helm chart pkg/operator/data/charts/redis
• '.reuse/dep5' seems be deprecated

full warrning:

/opt/venv/lib/python3.11/site-packages/reuse/project.py:332: PendingDeprecationWarning: '.reuse/dep5' is deprecated. You are recommended to instead use REUSE.toml. Use `reuse convert-dep5` to convert.
  warnings.warn(

  warnings.warn(

fix can be:

1. update the files and replace APACHE-2.0 to Apache-2.0
2. conver the '.reuse/dep5' to REUSE.toml. ( over command reuse convert-dep5 )

after that we will have the project is compliant with version 3.3 of the REUSE Specification
