Conversion from TOML to JSON still omits empty tables

[kiwi-oss]

Describe the bug
#1924 was an issue where empty TOML tables haven't been converted to empty JSON objects. It has been supposedly fixed and closed, but it turns out that the fix isn't complete. It seems that empty tables are omitted from the output unless an empty table is the last table in the input. That's why it works for input containing only the empty table which is the only case for which a test has been added in the fix pull request.

Version of yq: 4.47.1
Operating system: Linux
Installed via: binary release

Input TOML
input.toml:

[firstEmptyTable]
[firstTableWithContent]
key = "value"
[secondEmptyTable]
[thirdEmptyTable]
[secondTableWithContent]
key = "value"
[fourthEmptyTable]
[fifthEmptyTable]

Command

yq --input-format toml --output-format json input.toml

Actual behavior

{
  "firstTableWithContent": {
    "key": "value"
  },
  "secondTableWithContent": {
    "key": "value"
  },
  "fifthEmptyTable": {}
}

Expected behavior

{
  "firstEmptyTable": {},
  "firstTableWithContent": {
    "key": "value"
  },
  "secondEmptyTable": {},
  "thirdEmptyTable": {},
  "secondTableWithContent": {
    "key": "value"
  },
  "fourthEmptyTable": {},
  "fifthEmptyTable": {}
}

Thanks a lot, I'm confirming that this fixes the issue in the use case in which I noticed it!
