fix: use topic separator for deprecated alias warnings in help

[myarmolinsky]

Makes the warning for deprecated aliases here:

core/src/help/index.ts

Lines 202 to 206 in cc8366a

	if (command.deprecateAliases && command.aliases.includes(name)) {
	const actualCmd = this.config.commands.find((c) => c.aliases.includes(name))
	const opts = {...command.deprecationOptions, ...(actualCmd ? {to: actualCmd.id} : {})}
	this.log(`${formatCommandDeprecationWarning(toConfiguredId(name, this.config), opts)}\n`)
	}

use the topic separator by passing actualCmd.id into toConfiguredIds and using that result for the to in the Deprecation type parameter of formatCommandDeprecationWarning as done here:

core/src/command.ts

Lines 311 to 315 in 66604a3

	if (this.ctor.deprecateAliases && this.ctor.aliases.includes(id)) {
	const cmdName = toConfiguredId(this.ctor.id, this.config)
	const aliasName = toConfiguredId(id, this.config)
	this.warn(formatCommandDeprecationWarning(aliasName, {to: cmdName}))
	}
