Warning: `unused manifest key` `plugin`

[josecelano]

Relates to: torrust/torrust-tracker#1230

When I run cargo chef I get warnings because the modified Cargo.toml files contains and unused manifest key called plugin:

[lib]
plugin = false

[[bin]]
plugin = false

[[bench]]
plugin = false

[[test]]
plugin = false

# ...

I guess is something you used that cargo does not but I thought it was something wrong in my configuration.

The warnings seem ignorable, but still annoy me
