Add built-in function to convert RFC3339 to Unix timestamps

[SayakMukhopadhyay]

Some providers outputs unix timestamps and some other RFC 3339 where some providers input unix and others RFC 3339 and I need to convert between the 2 formats when passing outputs to inputs. I am using YAML only as I want to keep using declarative syntax. Hence, based on the discussion I had in the community slack (ref: https://pulumi-community.slack.com/archives/C037PV12W6L/p1715335945150989) with @t0yv0 .

I don't have much experience with the inner workings of this repo and am mostly using toBase64 as an example to write this.

PR is now waiting for a maintainer to take action.

Note for the maintainer: Commands available:

Rather than adding this as a builtin to yaml it looks like it would fit as a function in pulumi-std (https://github.com/pulumi/pulumi-std). We're trying to prefer helper functions in there rather than specifically in yaml as it allows other languages to benefit from them as well.

Thanks @Frassle - I apologize for directing to the wrong repo, I wasn't quite up to date on this.

[SayakMukhopadhyay]

@Frassle Thanks for directing me to the correct place. I will close this PR and create a new PR from the std package. Just one question, the std package isn't in the registry right? Although there is some docs in the repo itself, I don't see any docs in the pulumi website or it might be an oversight on my part.

[t0yv0]

Good call, we'll have a look! pulumi/pulumi-std#55 thanks!

[SayakMukhopadhyay]

In the meantime, I will work on adding the functions to std anyway since I can install the provider just fine. Thank you for the quick responses. I will probably be able to create a draft PR before bed.
