fix(metube): Remove metube custom versioning definition (#39023)

**Description**

Starting from version 2025.07.31, metube now uses `.` separators in
version instead of `-`, which renovate will recognise without needing a
custom versioning definition. This PR removes the custom definition so
renovate will pick up new available versions of metube.

This change should only affect renovate's processing of metube
versioning information; I have marked as 'bugfix' although it's driven
by an external change by the metube dev.

**⚙️ Type of change**

- [ ] ⚙️ Feature/App addition
- [x] 🪛 Bugfix
- [ ] ⚠️ Breaking change (fix or feature that would cause existing
functionality to not work as expected)
- [ ] 🔃 Refactor of current code
- [ ] 📜 Documentation Changes

**🧪 How Has This Been Tested?**
There are other charts such as Home Assistant which use the YYYY.MM.DD
versioning system which renovate can recognise without a custom
versioning definition, so it is expected this change will be successful.
