Rollup merge of #102075 - notriddle:notriddle/content-methods-method, r=GuillaumeGomez

rustdoc: remove no-op CSS `.content > .methods > .method`

# `font-size: 1rem`

This rule was added in 22dad4b, back when the `method` class was attached to headers instead of DIVs that wrap headers.

Old method rendering:

https://github.com/rust-lang/rust/blob/a96247bcac385671757034bd928c13097fd2ce76/src/librustdoc/html/render.rs#L2062

Current method rendering:

https://github.com/rust-lang/rust/blob/432abd86f231c908f6df3cdd779e83f35084be90/src/librustdoc/html/render/print_item.rs#L721

# `position: relative`

This rule was added in 88fe6df to assist in position the hide/show togges on methods. This is no longer needed, because these toggles are no longer implemented as absolutely positioned links nested inside headers.
