Merge pull request #17416 from tricknotes/fix-doc-markup

Fix doc markup for `NumberHelper`
Deprecate the `only_path` option on `*_path` helpers.

In cases where this option is set to `true`, the option is redundant and can
be safely removed; otherwise, the corresponding `*_url` helper should be
used instead.

Fixes #17294.

See also #17363.

Call value methods when merging relations, rather than accessing keys

The change to accessing keys directly was originally added to allow
`merge` to take a hash. The implementation of `HashMerger` no longer
requires us to be doing so. Accessing the values directly makes it
impossible to change internal storage details, even if shim methods are
added temporarily
Fix uninitialized ivar warning in tests
Remove unneccessary default values from relation merger

The value methods will default to an empty array for us automatically
let's warn with heredocs

The current style for warning messages without newlines uses
concatenation of string literals with manual trailing spaces
where needed.

Heredocs have better readability, and with `squish` we can still
produce a single line.

This is a similar use case to the one that motivated defining
`strip_heredoc`, heredocs are super clean.
Implement #== for column

We shouldn't rely on reference equality of these objects in tests
Implement hash equality on column

The query cache uses bind values as hash keys. The current
implementation relies on reference equality for hash equality. This is
brittle, and can easily break in the future.
💣

We were relying on hash inequality in tests
