[Bug] Plugin dependencies added to rocks.toml when updated

[NTBBloodbath]

As the title says, whenever a plugin dependency gets updated through :Rocks update, it is added as a new entry to the rocks.toml entry, causing some unexpected junk entries.

This one is a bit more hard to reproduce so I cannot really give reliable reproduction steps here, hope it's not a blocker!

@NTBBloodbath can you add some of the junk entries that were added? 🙏

Uhh one example could be nvim-nio which recently got an update and it's one of our dependencies.

The rocks.toml looks something like this after running :Rocks update:

[plugins]
# .....
nvim-nio = "1.6.0"

If you remove the newly added nvim-nio entry nothing happens, so it's not something that can be reproduced over and over again so I guess testing will be hard for this one 🫠
