Add deps tree functionality

[Ramkarthik]

Related to #3267.

Modified it to gleam deps tree based on the conversation in #3408 to make it more inline with how cargo tree works.

Currently supports gleam deps tree, gleam deps tree --package PACKAGE_NAME, and gleam deps tree --invert PACKAGE_NAME

Sample output (project name: deps_list):

1. gleam deps tree

deps_list v1.0.0
├── gleam_regexp v1.0.0
│   └── gleam_stdlib v0.52.0
├── gleam_stdlib v0.52.0
├── gleeunit v1.2.0
│   └── gleam_stdlib v0.52.0
└── pog v3.1.1
    ├── gleam_stdlib v0.52.0
    └── pgo v0.14.0
        ├── backoff v1.1.6
        ├── opentelemetry_api v1.4.0
        └── pg_types v0.4.0

2. gleam deps tree --package pog

pog v3.1.1
├── gleam_stdlib v0.52.0
└── pgo v0.14.0
    ├── backoff v1.1.6
    ├── opentelemetry_api v1.4.0
    └── pg_types v0.4.0

3. gleam deps tree --invert gleam_stdlib

gleam_stdlib v0.52.0
├── deps_list v1.0.0
├── gleam_regexp v1.0.0
│   └── deps_list v1.0.0
├── gleeunit v1.2.0
│   └── deps_list v1.0.0
└── pog v3.1.1
    └── deps_list v1.0.0

Please let me know if I should change anything.

Wow! Fantastic work! And the code looks really very good. Thank you.

I've left some very small notes inline

[lpil]

Would be nice to show the format of the output here!

[Ramkarthik]

I've added a sample output, not sure if this is what we're looking for. Please let me know.

[lpil]

Remove the optional bit for these two comments please 🙏

[Ramkarthik]

Yes, removed this

[lpil]

Perfect!!

[Ramkarthik]
