Releasable is too strict

[AlexDaniel]

<jnthn> releasable6: when is the next release, kind bot?
<releasable6> jnthn, I cannot recognize this command. See wiki for some examples: https://github.com/perl6/whateverable/wiki/Releasable

It should give the right answer as long as “next” or “when” is in the message.

It should also allow typos (like most bots do):

<El_Che> releasable6: stztus
<releasable6> El_Che, I cannot recognize this command. See wiki for some examples: https://github.com/perl6/whateverable/wiki/Releasable

Or maybe even other stuff: https://irclog.perlgeek.de/perl6-dev/2018-04-23#i_16081342

<stmuk_> releasable6: are we there yet?
<releasable6> stmuk_, I cannot recognize this command. See wiki for some examples: https://github.com/perl6/whateverable/wiki/Releasable
